Ant-Man: My guys disabled S.H.I.E.L.D. H.Q. security and cleared one of the vents, so we should be able to get in, and see exactly what's going on under the campus.
Black Widow: "We" being you and a bunch of ants?
Ant-Man: Fury watches you more than anyone, so you need to be anywhere but there. So yes. "We" means me and a bunch of ants. Technically, they're a colony.
Black Widow: Great.
Ant-Man: Good news is we found a new vault, an underground elevator, and some sweet souvenirs. Bad news, they replaced the vaults with Vibranium. Absorbs all sound and energy, and is basically impenetrable.
Black Widow: Why do they need an underground elevator? And why is he secretly replacing everything with Vibranium? It's weird...
Ant-Man: I shrink and talk to ants. Odin rides a bridge made of rainbows. Weird is the new normal.
Black Widow: I know something bad happened here a long time ago, and whatever caused it is in one of those vaults. I need to figure out what it is before it happens again...
Ant-Man: Well, good luck with that. Hit me up if you ever wanna steal something.
