Hmm. The eldest seems to be the only one so far who has been indicated to have genuine connection in the past. Her wounds are also interesting, but considering she willingly hurts herself, there's a good chance they're self-inflicted. At the least, she didn't threaten or hurt him, nor appear to be wanting to score a victory over her sisters as a primary motivation.
4th and 1st seem like the closest things to allies he has here. 1st could be the mastermind of all this, of course, since she actually seemed happy to see him again. But she also is the only one who's had an audience aside that cast her in a better light rather than a crazier one.
