“As far as escape attempts go, that was one of your weakest.”
Whumpee knowing they didn't have a chance this time, but trying anyway. And they'll try again, no matter how low their chances of getting away.
Because they can't give up. No matter what Whumper does to them, they'll keep trying. They're a fighting spirit, and if they stop, they might as well be dead.
(Whumper is just amused. They usually stop trying after a few attempts, if they try at all. Whumpee is different. It almost makes them sad when they break and stop.
Almost.)
