no i think she does love and trust glimmer quite a lot. she's also just overprotective, cause, you know. the horde killed her husband. glimmer's vouching, combined with adora's own apparent earnestness, is enough to get adora in the door, but if adora actually does sell them out, or let glimmer down, then angella is going to be pissed both as the leader of the rebellion and as glimmer's mother. and also i think angella and everyone in the rebellion is quite aware that adora and she ra are the same person?
