So I doubt their goal is just to kill us all. (I am probably 70% sure that is not their goal. )
So. Let's talk through this.
Who is confirmed to be a zombie? Is there some pattern? Of those who are zombies, who have we taken out? Who has been bitten or scratched and how long ago? Has everyone with a serious non-zombie induced injury spoken to Drs. Culber, Strange, Grey, or Temple?
And since zombies seemed to have popped up in homes and it's been a few days of the undead crashing our cars and pummeling our rosebushes. Does anyone need or want a place to stay? Should we look into safehouse(s)?
And can someone take care of Tony Stark when you see him?
