Don't have anything to add. Everyone's advice is great. Even though the situation's a bit more complicated, I'd still go with "assassin posing as a pizza boy" because it makes more sense at first glance and we don't need to get the underlying dynamics just yet (plus the other way makes it seem like someone's on her doorstep with a sniper gun, who kicks down the door as she tries to run, then pulls a pizza box from behind his back and says "That'll be 17.95."

)
Just wanted to say though that this sounds AMAZING and with everyone's fixes it'll be CRAZY AMAZING. You've got so much voice and this is so much fun! Love it!!
