actually this file setup is taking a lot longer than anticipated and I have time to write some shit
JASPER: Devon has let me know that she thinks, while the Super Soldier Serum does grant immunity and accelerated healing, it is still pretty likely for the super soldiers to get sick. So that'll happen. It won't be a while/he'll probably show symptoms late, so until then: obviously helping out SHIELD, probably as Cap as a public rallying point? Are SHIELD using him like that?, then is likely to get Super Militant and not give a crap about straight up murdering people who step out of line. Obviously this will play into long-term super soldier side effects, so it's not directly plague related, but it can be a thing that happens to/around you. When he does get sick, uuuh...I'm not sure. He is a needy sick person, but he is not my hypocrite and might sequester himself somewhere? I don't know what his solution for that is yet. Unless he has also infected friends that he hadn't at that point forced into quarantine zones.
TONY: Since the whole point of Extremis is adaptive repair, I'm pretty sure he can't get sick. He's also not a biologist in any way, but like the zombies he might be useful to create a dispersal system if we come to a cure solution. He'll be very hands on helping where he can, but most likely he'll be like the Wizard of Oz up in some tower somewhere controlling the Sphere modulation to adjust population distribution/quarantining/unattended systems like sanitation. If you are the type to take advantage of this with some kind of gang law system, he will probably be up your ass, but not necessarily as an enemy, depending on how you work. But also clearly playing for SHIELD when it benefits his goals, too. So that could be fun.
STRANGE: idk at what point in this he will be ready? If so: not a sick. Medical doctor, but can't practice surgery, so he might become a personal triage point in a personal quarantine area of magic. This might be a Strange Fist team opportunity.
