Why wouldn't it be believable? Small-town girl gets called up to the biggest group of Supes in the world. And the "#2 guy of the group" threatens to kick you out on your first day? It's all about the gullibility factor, in my opinion.Speaking of that character, I don't like the whole "me too" scene. It seemed very forced, out of character (for starbright or whatever the fu k her name is) and just kind of random. I mean, I get what they were doing. But after getting to know the female character it doesn't seem very believable that she'd do that.
You could even tell Maeve had to go through it.
Starlight didn't turn into what she became until after the churchy expo. Hughie was coaching her up, at first... but she was still timid.
