That is a staggering idiot ball. She's clearly standing there right next to several heroes Armsmaster has known for years - and Taylor was explicitly described as Glory Girl's 'friend' earlier. Not at least asking them what's going on before acting is just bizarrely dumb.
I'm sure you could work together a conversation that still has Armsmaster escalating to hostility without him coming off as a mustache twirling moron.
No this is just about right. How else do they get young parahumans into their organization? Threaten them with financial ruin. We already know from canon the PRT doesn't give a shit about anything except their image, the status quo, and getting more people Shanghai'd into their group.
Hopefully if Taylor joins a group its New Wave, I may puke if I read anymore Taylor joins the wards. This Armsmaster is just right.
