I think it was good for Rodrigo to actually experience some form of rebellion where there is a positive outcome, I really think he needed it because he's probably never ever broken the rules hence his robotic fear of how a housemate should behave. I got slightly scared when his face started twitching about there being a punishment but thankfuly he didn't go into jekyl/hyde mode!
I couldn't help thinking there would've have either been a spontanious combustion or mass window break due to his screeching if it had been him thrown into the pool instead of Marcus, but maybe after his adventour, maybe, he can take things with a pinch of sugar.
so funny that their space challenge costumes were actually needed!
