@Reishin no, Rikako is slapping Ren for not wanting to fight. she did not fight because she was taken by surprise, outnumbered, and isn't strong enough. Ren has a reason to be freaked out and a coward, he is the one not adapting fast enough and feels useless, I think he is a dipshit but the character hasa reason to be like that.
Ren deserved and needed that slap, though I think he may betray the group.
