@Zarathustra I have a feeling you just don't understand what you read. Let's start (again) with the fact that even the author constantly states that TJ is not a villain, but for some reason, pathetic haters continue to distort the plot and accuse him of all mortal sins.
Jason had been sick for a long time, so TJ understood that Jamie was scheming behind their backs. Someone had already prepared an attack on Ian before, and as we know, the culprit has not yet been caught, so there are clearly reasons to protect him. And where did the information come from that TJ was spying on Ian in the car? He just drove up to his house and saw him talking to some guy, so he decided not to interfere and left. But even if your words were true, it would be understandable, because TJ really, with the help of his subordinates, checks the environment of his loved one, and as we see, this is the right decision, because Jamie is trying to get to Ian through Chris and Joseph.
Now about the traitor, accident, car accident, etc. Jason is really worried about Ian, because he raised this child. Daniel himself is not a model of decency and even cheats on his wife with another guy, so why should he care about some kind of betrayal? Chiwoon clearly guesses about his boss’s feelings, but even he does not deny Yangi’s accusations (“I’m not afraid of this traitor”), so everyone can come to the conclusion what the gang thinks about Ian.
I can’t know what “restrain” meant, but it definitely wasn’t physical injury, and those guys admitted that they didn’t expect such an outcome (“Him falling from the second floor really was an accident”). Most likely, it was necessary to give him a lot of alcohol, as Ian himself said that when the fight broke out he was very drunk.
