Luna had to be cursed, captured, killed, buried underground, and kill herself twice before she ascended to the state of Savage Messiah and Egg-Giver. She also had to manifest her powers, and make it in an unquestionable way, which put her in danger of retaliation by the most powerful Orcs (which did come). Claire instead was just randomly bestowed the title of Saviour by the boss, and everyone went along with it; she didn't gain it, if not by not running away when she was offered it, for which she is being copiously rewarded ("very good terms").

Second, I've long had the impression that Claire isn't much of a character per se. I mean, she kinda was before becoming Marten's girlfried -- very nerdy, and a rather insecure, dedicated "straight man" that was trying to hop on the socialisation train. Afterwards, however, she generally struck me as being meant to be either admirable and in the right or adorable and supercute. There wasn't much room for a character at that point.

For me, the weird here is that Evanescence is being scolded for something she said, and not for the assault she committed. I guess it's how comedy works?
