Abby's smile faded when her sister looked at her with such a serious expression. She…wasn't joking about this? Abby looked away from her sister as she talked and tried to process what she was saying. It made sense but then again, it meant that her sister must have some sort of mental illness if she had an 'alter ego.' She'd read about things like that in the library before. It wasn't that common but it did happen from time to time and there were ways to treat it. What those ways of treating it were, Abby couldn't remember.
She pulled her blanket over herself and hugged it a little tighter when her sister started to get a bit sassy towards her. This really wasn't her sister. Physically, it was Mandy but mentally it really was someone different. This wasn't how Mandy talked - she was never this mean and blunt to Abby. And she'd never talk about Damon in that way - she was supposed to be in love with him and want to marry him. But this … person was bashing him.
She blinked a few times when she watched her sister pick up the couch as though it was a feather. Abby's jaw literally dropped and she stared for a few minutes. She didn't know what to say to her sister about this. "Uh.. oh….kay?" It came out more as a question than a statement but she wasn't sure what to think of any of this and she had just thrown so much at her.
