"It's--" Fine is not the right word, because it's not fine. Catra hates it when she's touched without warning and hates it even more when it's anyone but Adora (or it used to be that way). It makes her every nerve catch fire and begin to tell her that she is under attack and needs to fight or flee as soon as possible.

"Just don't so it again," is what Catra settles on. Distant enough that she doesn't have to acknowledge her own weakness. Her own worries. It seems a weak way to end it but she stands there, not sure what else there is to be said.
