Raven is obviously crazy for liking Beato, but he also seems like a pretty decent guy! He's also the only one who's actually given Battler any kind of explanation on the situation, so that definitely earns him some points as well. He also loses some points for clearly not sharing everything he knows, though at least he was more friendly about it than Lelouch. Basically Battler's opinion on Raven is cautious approval for now: they could become friends, but the situation is so complicated it's hard to know where it will go.

With Erika it's almost the opposite: Battler personally dislikes her and finds her unpleasant, but apparently they're on the same side in the whole mystery vs. fantasy thing??? He's mostly waiting to get more memories back before forming a concrete opinion on her, but (probably correctly) doubts it will change for the better.

Tiger also seems like a nice guy and a good knight! The Queen's game added to that impression too when he supported Battler's request for humane imprisonment. 'u'b
