Personally, I like the alternate viewpoint and depth that a companion character provides. And I also liked what you've done so far with her. Ultimately though, the choice of whether you'll keep her or not is up to you, so I won't impose really.

in all honesty, I would say Galen and Owen have the majority on this vote, as they do the most interaction. So if Galen likes it, then it is up to Owen... I could simply change her origins a bit so she is no longer an extremely divine thingy...
