When Rita grabs him, 9S lets out a startled yelp that quickly turns into an, "Ow!" when she whacks her head against his.

What was that for!? Except he remembers the last time Rita had hit him, and she was definitely the one who came out on the losing end of that.

"Rita, are you alright?" He reaches out to try grab her by the shoulders before she falls on him; he really doesn't trust her motor skills right now. "Maybe we should talk about this later, when you're not drunk."
