Really odd choice to do Robby like that
I legit hated this kid almost the second we "met" him. He was a rotten apple.
But he got a job (and truly liked it), got a mentor and teacher, learned karate, liked that, was exposed to a better way of life and given opportunities, and legitimately turned his life around.
He tries breaking up the fight that the psycho Tory was insistent on making happen. Even after he heard Sam say she kissed Miguel, I believe Robby even says, "Are you ok?" Again, this is right after he found out his girl cheated on him and he was still concerned about her safety. Then Miguel comes running in and tackles him, which started the brawl. To his credit, Miguel tried to end it by throwing in the towel/showing some mercy and the writers inexplicably have Robby retaliate - which is fine in of itself - but then Miguel goes flying over the railing and is obviously seriously injured.
Most people have the potential to lose their cool, so having Robby do it isn't the worst or most out of field writing decision. But the severity and having the whole cast of characters just completely and totally turn on him doesn't sit well with me at all. Feels completely and totally unjustified. It starts with the beginning of the finale when Daniel says taking him in and training him was a mistake. Daniel's kid was missing, so his anger was justified - and he thinks Robby is to blame because Robby says he is - but to just outright write the kid off was fucking cold; especially since he took the kid in and let him live with his family. Even after that, Robby sticks up for Daniel to his Johnny; again showing what a good kid he's turned into. Then, as I mentioned above, he not only tries to break up the fight, but asks Sam if she's ok AFTER hearing she cheated on him. Then Miguel ATTACKS him. Miguel (and Tory) started the brawl. Daniel turns on him. Sam turns on him "Robby, what did you do?!" I'm not saying he should get off scott free for what happened to Miguel, but how is the show gonna do this kid like that? And why is no one talking about it?
