Wilbur rolls his eyes. "I'm just patching you up out of some misplaced sense of guilt or nostalgia or whatever; after this, you can try and arrest me again as much as you want-"

Wilbur's face darkens. He reaches out a hand, rubbing absently at a long slash going through his trench coat, a tear in the seams of it all. Tommy stills.
"No," the villain finally mutters with a brittle laugh. "No, you don't."
