Thanks.
The Psycho Pirate's mask's ability to affect emotion could have been incorporated by the Sanctuary AI as a form of treatment (and then turn out to be a band-aid rather than proper treatment and healing).Just thought of this, the masks make me think of Psycho Pirate. And his powers (via the mask) would certainly make this story interesting.
It's strange that Superman is on the scene confirming deaths but not providing any info on causes etc. Yes, he's not Batman, but he's still a walking crime lab and can provide some info on what might have killed so many enhanced people.
Separately, I'm starting to wonder: what if this is Sanctuary working through the worst fears The Trinity have of Sanctuary and it's all them being treated?
