"Just reward"? I wouldn't (quite) say so, Dave. One could proffer so many scenarios into the event(s). Pissed off? Playing? Got carried away but realized the trainer was in danger and brought him back up and held him above water until he was well recovered? Various points of conjecture.

"Captivity"? The only point I "believe" is that wild animals should not be held in captivity other than for study and research. I cannot go to a zoo without weeping. When I see a wolf or some such animal pacing back and forth I just wanna throw the bastard in charge of such cruelty in the cage.

Unfortunately, freeing the animals won't happen. Too much money to be made... the bastards.
