Wanda- Will be in Hell for a bit but can get involved when she gets back. Also, she's still gotta find Billy and do all that, too, which we could probably incorporate somehow?
Danny- I don't think it would affect him with his chi stuff and if Strange is around I'm so down for the Strange Fist thing on this, like he'd definitely be doing everything he could to try to help people.
Nick- Super soldier too so I guess Nick'll likely get sick eventually. Until then he's available for anything he's needed for.
Peter- So we talked about the Guardians above, but if even Super soliders get sick, I can't see why Peter wouldn't, too.
