I have to say, you've definitely made the right choice letting the Wall-man into your headspace, babe. Sure, it would've been better if I'd gotten here before Rob...Robinned it all up but I'll carve out my own space.

The company's good, so if you just provide the food and entertainment, I think we'll get along fine. You are going to let me out, right? Keeping a speedster locked up probably falls under "cruel and unusual punishment."
