(Time Skip)

Mugman and the others stepped into their house. Mugman looked around- he looked lost for about 3 seconds.

"Make yourself at home, you'll be living with us for now on," Karla smiled walking into the kitchen," I'll make dinner- I'll let you know when it's ready,"

"Ok, Mom" Marcilene smiled walking away from Mugman.

Mugman stayed put as the others walked in different directions. Not sure what to do, he stood still- not moving from his spot.

Maurice noticed Mugman didn't move, "Hehehe, you can explore if you want,"

"Huh? Ummm, I don't-

"Oh don't be shy- go ahead, we insist" Maurice giggled.

"Oh- ok then, "Mugman said awkwardly throwing himself into a random room.

It was the living room, a soft couch sat against the wall, inches away was a drawer and a flat-screen, on a wall near the TV was a small fireplace.

"Whoa." Mugman muttered, "Cozy," he said to- (CupheadMccupette: Absolutely nothing) T_T himself.

He then plopped down on the couch, his mind suddenly going blank (You know that moment where you're so relaxed that your mind goes blank, then you just freeze? That kind of moment).

"Whatcha doin?" A voice asked from the side of the couch.

Mugman jumped, startled by the scare, "Huh!!!"

"Oh, sorry- didn't mean to scare you," Marcilene laughed sitting next to him.

"It's... it's alright. So... you're my sister?" Mugman asked.

"Yep"

"So- what do I call you?" He asked nervously.

"My name is Marcilene- but you can call me Marci" Marcilene replied smiling.

"Oh- ok then-" Mugman muttered looking down shyly.

"Why are you acting like that? We're your family! You should be smiling, happy, relieved you're not with that fiend you call family." Marcilene said quietly.

Mugman angrily sighed, "You guys must really hate him"

"It's not that we hate him- we just don't trust his kind," Marcilene said as Mugman held a pillow up to his chest.

"Your father seems like he hates him,"

"He's your dad too- and yeah- he did make it seem like that, but that doesn't explain why you like him," Marcilene said glancing over.

"I grew up with him, he and I held onto each other on cold nights, we ate together, we played together, I took the blame 100% of the time- but he would stay in the room with me when I was grounded, and when I would have a nightmare- he'd let me sleep in his bed, when I was feeling down, he'd let me borrow his favorite teddy bear until I was happy again, he would even reject anything given to him and stay with me until I was smiling again. He was the closest friend I was able to call- my little brother- until... until you guys showed up then- our relationship suddenly turned into nothing." Mugman whispered his words getting lost as he cried into the pillow.

"Wow... you guys were really close," Marcilene smiled weakly, guilt hitting her hard. She quietly looked down, realizing the Cup her family believed to be evil- was actually a piece of Mugman's life, "I'm sorry, Mugman"

"My own parents don't even want me to see him! I-I walked away! I didn't even look at Cuphead! I didn't look at Elder Kettle! I just left. They... they didn't want me to leave- I let this happen, I-I... Ugh! I'm so stupid!" Mugman wailed as his sister hugged him.

"It's ok Mugman, it's ok- I'm sure they understood" Marcilene whispered landing a kiss on his forehead.

While that was happening, they didn't know Maurice and Karla were standing outside of the doorway- listening to the conversation.

They both looked at each other, "What do we do? We're losing him" Maurice asked seriously.

Karla's face darkened as she leaned forward, she then whispered, "You take out the Cup and then... 

pay the Devil a visit"
