It was like this Isabella and Farlan found the two.

"Big brother~! I'm home~!" Called out Isabel, full of energy and eagerness, as usual. She went to sit by Levi, but froze when she saw Eren, her head still laying on Levi's lap. Farlan soon entered the room, smiling as always, glad to be home. "Hey! Levi! You'll never guess what happened today! A massive fight broke out and one kid got-" he broke off his story as he too, saw Eren.

After the shock had faded, they both asked in an excited whisper "Levi, is that you're girlfriend?"

Levi smiled. "Actually, not to disappoint you or anything, but she probably doesn't even see us as friends."

Isabel and Farlan looked a Levi's smile, astounded and speechless for once. They hadn't seen Levi smile since... "Then why is her head...?" Started Isabel gesturing at Eren's sleeping body.

"It's a long story." Levi said, a little stiffly. His siblings were way too excited to notice.

"Tell us every detail!" Farlan half-shouted, lightly punching his younger brother in the arm.

"Well..." Levi edited the story a bit, remembering his promise. "I found her behind the buildings during lunch and we talked for a bit. I asked her about her jumper and she went a little rigid. So I said something along the lines of 'You don't have to tell me. You probably think I'm just some popular jerk', and she replied with 'I don't think that at all'. We kinda stayed there until the final bell rang, so we skipped some of our classes." He admitted reluctantly. "She rushed off somewhere, so I followed, not that she knew. She got hurt before leaving the school grounds so I helped her. I asked 'do you want to go to the nurse's office, even though she's probably left by now, or my house?' And she replied with my home. Once we got here though, she had a change of mind and left." He paused to take a breath.

Farlan and Isabel exchanged curious glances. "That still doesn't explain why she's here." Isabel prodded.

"Funny thing, as few seconds after she left, she knocked on the door and told me she didn't know how to get to her house from here. I let her in and she started asking questions about you two," he said, gesturing towards the photos, "and then she asked if our parents... If our parents took the photos or didn't like being in them. I... Started to cry. She apologised and I told her that they died, though she didn't let me tell her any more than that. She comforted me and... Fell asleep I guess."

"Hmmmm..." Isabel was shocked that Levi actually mentioned their parents. He never did. This girl must be interesting, she thought. Farlan was surprised too, but didn't 'hm' or say anything.

"Hey Levi, do you like this girl?" He asked after a few moments of silence.

Levi didn't say anything, a blush creeping into his face. Farlan smirked.

Isabel, oblivious to Levi's blush, piped up. "So what's her name?" Before Levi could answer, Eren started to stir. Yawning, she lifted her head off Levi and stretched. Still groggy, Eren mumbled something about her pillow being too hard, and Farlan thought he heard something along the lines of 'something prodded my head'. He stared, amused, at his younger brother.

"Good afternoon, angel~!" Isabel greeted cheerfully.

"Isabel!" Levi exclaimed, slightly embarrassed. Eren blinked, taking in her surroundings.

"Angel?" She saw the grin of another, smaller and younger looking girl, before exclaiming "Oh!" She immediately felt awkward."You must be Isabel and Farlan! I'm Eren. It's nice to meet you both." Eren said in a rush. Isabel giggled at the girl's awkwardness.

"You are very cute! I can't wait until you're my big sister!" Isabel seemed excited at the thought of a sister, once again oblivious to a blush, one that seeped colour into Eren's cheeks. "Big brother Levi, treat Eren well, or I'm never speaking to you again!" Isabel said in a childish huff, still managing to sound serious.

"I promise to do exactly that." Levi said sincerely, looking Isabel right in the eyes.Farlan watched, amused, by the exchange.

After making sure Levi meant it, Isabel turned back to Eren. "Big sister! Come see my room!" Isabel dragged Eren by the hand, leaving Levi and Farlan alone.
