"Of course I'm going to worry about you," Strange almost instantly responds. "We're friends, that's what friends do."

But an airship? That's certainly a plan. Granted, it's a plan that Strange would never think of for himself, but he can picture Billie being a sky pirate. In fact, he can picture it almost too easily.

"Once Red gets big enough, you won't need an airship. You can just ride him over before doing your highwayman routine." Airwayman? Strange doesn't know what you'd call a sky pirate, so he just brushes it off.
