Out of the two, Yay! Personally, I'd prefer Rey to leave the group and Ralyks to continue with them, but if that's not an option, I'd rather he come clean rather than continue his dual identities. Either way, I'd like for Rey/Ralyks not to try juggle two identities with the group at the same time.
Ater is absolutely right, the longer he continues to hide it, the more it compounds and the bigger the blow up when it does finally come out, especially with Alicia. He needs to come clean. If he does it well enough, it might not be so bad (minus the killing people but he doesn't have to tell them that). He had his reasons for hiding in the beginning (the way he was treated, betrayal by billy, skepticism with the royal court, his skill rank, etc), then he got his class and didn't want to lose it by exposing himself and he also wanted to advance it, so on and so forth. he has legitimate reasons for why he did it, if he goes about it right it shouldn't be that bad.
