The sound of Steve's voice caught her off guard more than the fact that Olivia hadn't realized when he'd walked into the kitchen, let alone taken to leaning against the counter opposite of her. God she really needed to rest, her brain was only functioning on fumes. Her response time to Steve's initiation in conversation was only further proof of that. "Ah, yeah no problem. Thank you for buying dinner." She had managed a smile but she ended up biting her lower lip out of an old anxious habit that she wasn't necessarily conscious of. 

"Oh yeah? It is pretty good, better than most I've had despite me not being much of a pizza connoisseur like some I know." Her eyes flickered to her sleeping sibling on the couch, obviously a teasing jab at him until she shifted her gaze back over to Steve as well. Maybe it was a teasing remark to him too but maybe it wasn't. Taking another bite of her pizza it appeared she was more alert than she had been before Steve had come into the kitchen but she still seemed thoughtful. Her brow furrowed as her gaze shifted downward, obviously crafting her words carefully in her mind before she spoke, 

"I, uhm, really appreciate you being a such a good friend to Ethan. I'm glad he has at least one person to lean on through all of this... mess." For lack of a better word. She cleared her throat softly before smiling again. "It means a lot..." Before things began to tread on the thin ice of emotional instability for her she changed the subject, "And ... I hope it's not weird having a female in the house for you. I mean, I don't know if you have any sisters or anything but I'm basically a wallflower and growing up with Ethan there isn't anything I haven't seen, smelt or heard so don't mind me." 

Olivia's change of subject just ended up with her blabbering on about a topic that shouldn't really be much of a concern considering Ethan's reassurances that it would just be as if she had another older brother living in the same space. Yet, she still felt the need to let Steve know that he could be completely himself and comfortable around her without any complaint from her. A part of her empathized with how strenuous and or awkward it could be with a younger female in the house with two older men but she was determined for it not to be that way.
