You have to kidnap her pet squirrel from Stark Tower where she is staying with the avengers. They are having a party.
You have CIS on your side, which means that if people try to hit or shoot you, they automatically miss. However if they purposely don't aim for you directly, there is a chance something will hit you if nearby. If they are smart at all, it won't take them long to figure this out. Doreen is petting her squirrel in her lap and is sitting at a sofa with Iron Man and Hulk.
How do you do it? Your outside at the bottom of Stark tower. You get a month of prep inside the Marvel Universe before you act on your plan.
The week after: You hold the squirrel for ransom, to get paid by Doreen. Turns out she is wealthy LOL. But Doreen shows up with Iron Man, Hulk, and Thor.
What do you do? Hope you have prepped for this LOL.
