Not even a real name. But who was Scott to judge? Maybe this guy was actually a doctor. And his last name was actually...Strange. This would not be the most difficult thing to believe at the moment.
"Well nice to meet you and thanks for the, uh, gift box?" Lang eyed it suspiciously once more as Strange continued to talk about the other Avengers. He even began to open it before stopping to look up. "Oh, that's great. Maybe now there's no reason to..hide." But Scott wasn't really an Avenger. He was the guy Sam called because Cap needed some help finding the other Super Soldiers that were about to go destroy the rest of the planet.
Except, they didn't fight any Super Soldiers. Just the other half of the Avengers because apparently they hadn't been getting along? That information would have been great but hey. When Captain America needs your help, right? "I'll reach out in case they need me again."
