"What have I told you about taking the interspace-time teleporting manipulation watch?" Sonny's mom says angrily through the watch making her laugh.
                         "That it was still unstable from when Uncle Jean went back and saved Uncle Marco and that if we used it we may get stuck somewhere we can't get back from," She recited as if she had written it down. "When did you install this communicator?"
                          'So they saved Marco!' Hanji thought happily. While Levi was shocked by everything that is happening in front of him.
                         "It's always had it I had the idea before I made it because there had been nothing else like it. Anyways where and when are you?" The voice asks sounding more alert.
                         "Um I went back to your home world," Sonny answers shyly as her mom gasps loudly.
                          "Preston!" A girl screams through the watch making Sonny cringe and Preston laugh.
                          "Hey sis," Preston says calmly to his sister on the other side of the watch.
                         "I told you she was nothing but trouble! Why did you go with her?" Layla asks loudly making Sonny pout and Preston kiss her cheek.
                      "I knew I couldn't stop her and I wouldn't let her go by herself, also I had been wanting to see where mom and dad are from in person also," Preston confessed smiling down at his girlfriend in his lap.
                        'So both his parent are from here, too?' Hanji questions herself internally.
                        'Who are these kids?' Levi asks himself still in shock. Then he hears footsteps behind him so he turns to see Eren coming as well.
                        "Hanji you're out here again?" Eren whispers hiding behind the bush with them.
                          "Of course," Hanji says laughing softly while still staring at the couple as Preston's sister rants through the phone.
                           "Hey Brat, what are you doing out here?" Levi asks Eren slightly shocked he already knew to hide.
                           "I had gone to your office to ask about tomorrow's schedule but I couldn't find you so I was going to ask Hanji. And after last night I kind of predicted that she would be here," Eren whispers while looking at Levi who just nods with his regularly blank face.
                             "Enough! Preston get your butt back home so I can ground you and Sonny you better not do anything like this ever again especially with my son!" A loud woman's voice yells through the phone making Preston freeze looking terrified.
                             "H..i Mom," Preston says rubbing the back of his neck with the arm that isn't tightly wrapped around Sonny's waist.
                            "Mikasa, Honey please calm down and please don't break the system," A calm male voice floods through the watch making Sonny laugh softly.
                             'What!?!' Eren thinks shocked at who the voice belongs to.
                              "Armin, our son is in another universe during a different time! How are you not worried?" Mikasa's voice says angrily.
                           "What!?!" Eren whispers aloud to himself causing both Hanji and Levi to turn and look at him.
                             "Armin, control your wife before I make her shut up myself," An irritated voice comes from the watch making Sonny laugh loudly.
                          "You wanna go shorty," Mikasa's voice says tempting the man.
                           But before anyone could say anything Sonny happily says, "Uncle Levi!"  
                            This causes Levi to gasp and stare at the couple from behind the bushes. Also shocked by hearing his own voice that isn't from his own mouth.
                            "Sunshine, how's it over there?" Levi's voice says to Sonny making her grin widely. This causes all three adults to gasp from behind the bush and then the two look at Levi in between them.
                           'Levi's nice?' Eren wonders smiling slightly.
'I'm nice!' Levi thinks and looks over to see Eren smiling softly while looking at the ground. 'Maybe that's a good thing.'
                         "Same as ever, how were you ever so mean to Uncle Eren?" Sonny asks shocking both Levi and Eren once again.
                          "I have no clue but I'm glad I was during that time period. I had to make sure he stayed alive somehow," Levi's voice says softly to which you could tell he was smiling.
                           "I love you too," Another happy voice echoed through the watch. "So, Sonny when are you guys planning on coming back? I know Maria wanted to come and yell at you guys but she got food poisoning. Levi here made dinner last night but didn't thoroughly cook the meat so..."
                          "Hey I told you I couldn't cook, that's why I make you cook," Levi retorts trying to defend himself.
                           "Oh Levi I think Eren knows that, but he didn't marry you for your cooking skills," Sonny says laughing while Levi's voice grumbles over the communicator.
                            Eren chokes on his own spit while thinking, 'Married!?!'  He looks over at Levi to see him looking at him also in shock.
                             "Hanji stop pushing I'm trying to talk," Eren's voice complains through the speaker.
                         "When are you coming home?" Hanji's voice comes through the speaker causing Hanji to gasp from behind the bush to gasp again. She realized the same voice for herself is the voice of the mother of Sonny.
                         'I'm Sonny's mom?' Hanji thinks shocked but happy.
                        "I don't know mom the teleporting button broke on the watch," Sonny says softly waiting for the reply. Three loud shouts echoed though belong to Hanji, Mikasa, and Layla who were mad.
                       "How did that happen you used it once?" Hanji's voice was frantic now worry seeping though every word.
                        "Actually when we first got here Preston had let go and turned into a titan. So, I had to feed him Bertolt and have him turn back into a human. Then I went back to before that happened because it would change everything that will happen," Sonny finishes causing the three people behind the bush to be shocked once again at something she said.
                        "That means their still alive, oh no you need to get out of there before everything unfolds and more people start dying," Levi's voice says sounding worried.
                            "I don't want a dead brother, you better bring him back safely," Layla's voice echoes making Preston chuckle.
                           A gasp echoed from the other side of the watch making Sonny look alert. "I remember now you showed up a little after the 104th joined the survey corps," Hanji says then whispers something only the couple was able to hear.  
                            Sonny stands up from Preston's lap and walks toward the bush where the group is hiding just waiting to be found. When she looks over the bush she gasps and starts laughing at all their shocked expressions. "You were right mom, I can't believed you remembered that 19 years later," Sonny says shaking her head.
                         "Hi me!" Eren's excited voice echoes making the past Eren laugh and say hi in response. "Hi Levi," Eren says flirting with the past Levi making him slightly blush but push it away.
                        "Hey don't go flirting with my past self," Levi says jealously making Eren laugh as a new voice comes over the speaker.
                            "Hey uncle Levi why do you hurt Uncle Eren?" A little boy's voice comes through the phone making Sonny's face brighten.
                            "Ben!" Sonny says smiling brightly, the name makes Hanji laugh softly knowing it was her kid.
                             "I see what I did with the names," She says shaking her head laughing.
                             "Well, um I mean um I know Eren has titan healing powers so I know he'll be fine but I guess to make him stronger," Levi said for the first time being at a loss of words.
                          Sonny beckons them to get up and follow her back over to where Preston is sitting. She sits back on his lap while they sit around them. "Well I guess that's nice," Ben's little voice says quietly as it's led away from the equipment most likely.
"Hanji, I know you won't actually make it for a few years, but I need you to try and figure out how to fix the interspace-time teleporting manipulation watch. This is when you get the idea to build it so I think it would help to actually fix the finished product," Hanji's voice says through the watch making Hanji chuckle and nod her head forgetting she couldn't see her.
"Yeah I'll try," Hanji says smiling at Sonny. "This is going to be so exciting!"
"Hanji, Eren, and past Me please protect these two we don't want anything to happen to them," Levi says through the watch sounding genuine making Hanji smile.
"You can count on me," Eren says smiling at the watch making Levi next to him blush softly.
"Good and turn around," Levi says happily making Eren curiously turn around to see Levi blushing which makes himself blush in return. He leans in and shocks Levi my kissing his cheek causing Hanji to squeal.
A beep rings out and tears came to Sonny's eyes once again. "Mom the communicator is about to die and I don't know when we are going to talk next but just know I love all of you guys," Sonny says to the watch on her wrist. Multiple 'I love you's' come out of the watch making her smile.
"Love you mom, see you sis," Preston just before the communicator dies. And Sonny turns around and cries into his shoulder while silence fills the air.
Not knowing what to do Hanji stands up walking over to the couple and pats Sonny's back. "It's okay you'll see them as soon as I fix that," Hanji says point at the watch on Sonny's wrist. Then unexpectedly Sonny jumps onto Hanji hugging her tightly while trying to stop crying. Not knowing how to comfort her she awkwardly pats her back. After a little Sonny pulls away laughing at Hanji's actions.
                           "You've never been good at comforting people," Sonny says as Preston stands up and wraps his arms around her waist trying to calm her down. She takes off the watch and hands it over to Hanji who still just stares at her daughter. "I'm tired and I'm going to bed." Preston pulls back and grabs her hand while they walk back to try and get some sleep leaving them behind.
                             "My head hurts," Eren complains while holding his hands to his temples trying to soothe his pain. "All of this shocking information is just making my head spin. So, we all some how get to another world, Armin and Mikasa are married, they have two kids, you're married with two kids, me and...and Levi are married, we probably adopted a kid, Jean went back and saved Marco, and their married. Is there anything else I'm missing," Eren says summing up the whole conversation.
                 "Don't forget I invented this watch before anything even close to it was even made and Levi is nice in the future," Hanji says making Eren laugh and nod while Levi glares at her.
                    "Okay I'm done talking to you people. Bye Glasses, Jaegar," Levi says standing up and walking away as if nothing happened making them just roll their eyes and follow.

(By the way I don't actually ship Armin and Mikasa but thats how I chose to write this)
