I say time has a play into this. 4 years, he spent 4 years following after Derrick.There's utter devastation he does not want to experience. So Bruno is running away from the reality of having wasted time. Each time he's put in the position that lessens his chance of getting in he get anxious. He's aware the platform he's on isn't sturdy. Derrick's words aren't sturdy. So he's keep reminding Derrick. Time is running out. Derrick is aware and he holds that to him. He weaponizes it against Bruno because he feeds on it. To make him feel better. It's the inferiority complex he has. All he has is his parents name.
Their name is entry to abuse.
From how they're making it out to be the film/entertainment industry is tough to crack into.
So the immoral things Bruno is doing is because out of hope that it was worth something. That all he has done is worth something. He's desperate— for what explicit reason, I have no idea.
Hope Bruno doesn't continue though. Derrick hasn't given him anything concrete.
This is definitely an angle I didn't consider and gives Bruno a little more depth, but honestly like you say, Bruno is giving everything- which now potentially compromises his safety after Andrews threats. And getting nothing in return. He's making huge bets with nothing to back himself up. (Which I think mainly just makes this conflict a little juvenile to me, I wish there was something a little meatier cos I've come to enjoy the writing of Andrew and Luke's relationship). Even if Derrick has promised him something the dialogue he has with himself hardly seems like he even believes anything would be worth it. He's terrified of being found out and, as far as we know, there's no safety net for him if that ends up happening. He's a lap dog at best and not much of a compelling case as one, which is a little unfortunate cos I'm honestly all for a case of pathetically clinging to something that was never there, narratively speaking.
Maybe we'll find out on the coming chapters and it'll pay off nicely, but so far it's the only thing I'm kind of let down by.

Ok so up until now I'd assumed that Derrick had something on Bruno and that's how he's been able to get him to do all his bidding, but now we're here and there's literally no good reason for Bruno to be doing any of this. The spying on Luke and Andrew, the locking Luke in the room, the clinging to Derrick for dear life. Derrick has a poor reputation already and he hardly even has his foot in the industry door. If the reason Bruno keeps trying to vie for Derrick's good graces is to have an in to the scene.... what has made him think anyone would actually give Derrick the time of day? I get the rich parent connection nepotism thing but they also don't have him doing anything big.
