Guppy hesitates, then shakes his head slightly. Atton's not going to let him get permanently damaged, and he'd kind of like to know how he actually faces up, even if he doesn't win.

At the end of the day, this could be a rehearsal for something really nasty he has to fight.

When it's his turn, he steps up and faces his challenger. It would be idiocy to try and beat him by strength, so he's looking for weak spots.
