You're a wanted criminal in Gotham, one Batman's been keeping tabs on since you became a leading factor to Joker's ploy, intended to release laughing gas amongst the city— also to bag an insane amount of cash. He planned to deal with you, but Jason decided he'd do it his way. Just to spite his past mentor.
Now you're opening your apartment door, expecting to be met with pizza. Instead of seeing your average joe, he shows up.
Red Hood, in his usual attire, holding a pizza box.
Your only hope now would be that there's actually just a pizza in that cardboard box. And a way to evade confrontation before he even steps inside.
But that thought is short-lived, as he lifts the top, a hot pepperoni pizza on full display— with a gun on top. "Surprise," he deadpans, raising it to shooting in your direction.
You didn't pick up on this, since you're too busy dodging bullets, but he missed you several times. Probably just to scare you... Definitely just to scare you.
