[from trailer, Steve and Nat see Scott Lang, alone at the entrance of the Avengers HQ through a security camera
Hi! Uh, is anyone home? This is Scott Lang. We met a few years ago, at the airport, in Germany? I got really big.
Is this an old message?
Ant-Man? Ant-M - I know you know wh - I know you know that!
That's the front door.
That's me. Can you buzz me in?
