I've had a 2 AM thought! Although, you might not like it,
So aside from Chase, who's more like a brother, Robert has never had a friend. He was a homeschooled kid who spent all of his time training and then went into hero work young.
The opportunity to make a friend was not there, it was something he always wanted, but tried not to think about too much.
Suddenly, as a dispatcher of all things, he has an entire group of friends.
They're weird, funny, sarcastic, and the coolest people that he's ever met. The crazy thing is that they like him, they actually spend time with him. They remember the things that he says and go out of their way to talk to him. 
After beating Shroud, he's never been happier. He's finally found his people, who might even be his family and not just his friends.
Or, that's what he thought at least. Now he wasn't sure.
Let's say it had been an absolutely terrible day at work, the worst people were calling for the Z team today. Every Karen had a problem that had to be solved in just the right way, it was a nightmare for everybody.
The team were in the break room, fuming about the day and letting off steam and talking crap about their boss.
Robert, who had been on his way to the break room to try to cheer them up, stopped and listened in when he heard his name.
He listened as they tore him apart. Calling him every name under the sun, talking about how pathetic he is, how he should look for another line of work because clearly he's not made for this.
Hell the only reason he has this job is because he's too weak and pathetic to be a hero so he gets his rocks off telling real heroes what to do.
Eventually, they start calming down and admit that Robert isn't the problem. They were just mad, absolutely nothing they said was true. The real problem was the callers and it had to be really rough for Robert too. Robert is their friend and the best dispatcher they've ever had, obviously they didn't mean anything they said.
Robert didn't hear any of that, though. He didn't hear them start to calm down, he didn't hear them remind each other that they love Robert and that their anger was misdirected.
If they had known he had heard any of it, they would've bent over backwards apologizing and making sure that he knew none of that was true.
But they didn't know, and Robert didn't hear.
Which is why everyone was confused when Robert didn't come back after lunch. Nobody knew where he was, his phone was off, and he wasn't in the building. 
Before Z team really started to panic and report him missing Mandy called them into the boardroom. She didn't know where Robert was either, but she just received an email from him with his resignation.
Attached to it was a letter for the Z team, most of it was just Robert apologizing. He didn't mean to be in their way, he didn't mean to intrude, he didn't mean to invite himself into their lives where he wasn't wanted. He really tried his best and he's sorry it wasn't enough. He's even more sorry for not realizing sooner that he was holding them back.
He told them all that he was so proud of them for being the heroes that he knew they could be, despite him being in the way, they had really started to thrive. He's grateful he got to be even part of that and he's rooting for them.
Obviously, after hearing this, the Z team rushed to Robert's apartment, but it was empty. Not the furniture or anything big. The couch and bed they had gotten him were still there. But all of Beef's things and the little trinkets and keepsakes that Robert had collected, were gone.
Just like that, Robert was gone. 
Mmmkay, off to bed now. Byeeeee 😁
