You know what it does? [Tony doesn't wait for a response.] It hijacks your hippocampus and picks out your traumatic memories, projecting them onto a set. In essence, it makes you relive them. [And the memories that he's probably talking about aren't the kind anyone wants to relive.]

If you're looking to undo what HYDRA did to you, then- I don't know if there is a way, to be honest. [He pauses, weighing what he's about to say. There are about a thousand reasons not to, but Tony's never been good at listening to reasons why he shouldn't do anything. Which, to be honest, is how his life generally ends up in a clusterfuck.

But it's how he fixes things, too, doing what everyone else tells him is stupid. Risking it all on one dumbass idea.]

But if there is, then I'll help you find it.
