Oh, it's not Emma I'm worried about. She's just going to shrug it off through pure former supervillain stubbornness.

The problem with that interpretation is that Marvel telepaths are insanely powerful. Emma's one of the strongest and simultaneously most skilled, and mental manipulation is her area of expertise. She's controlled brains at the physical level before, doing stuff like triggering the pleasure centers of a mob to shut them down.

I don't intend to negate the event, and Emma's too selfish to go around curing everyone, especially because she's in the closet and telepathy is much harder for her here than it is back home, but I'd think if she were concentrating on someone, she could keep them clear-headed. She'd be limited in how many she could do at once, and it would tire her out, decreasing her limit as the event wore on, and if her concentration got broken or the person left the zone, they'd be on their own again. How's that sound?
