I was just thinking, The Z-Team doesn't know Robert's exact relationship with Shroud. (And truthfully neither do we.) Like we know that he was at the bbq, that he helped create the Astral Pulse, and he at least considered Robbie a friend. So it's safe to say he was around Robert a lot(I'm going with Uncle Elliot for this post....maybe more of Papa). But Z-Team doesn't know that.
So after the game, the Z-Team expects Robert to be happy. He finally stopped the man who killed his father and got his revenge, but Robert just shuts down after having the time to process. Doubly so if he kills Shroud.
The team comes to his apartment to celebrate but they find him in a worse state than after he woke up from his coma. He hadn't been eating, and hasn't been taking care of himself in general. And he's just drunk. And of course Z-Team starts to freak out. Trying to figure what's wrong.
After some pushing, Robert just sort of rambles on and on. On just how much Elliot had meant to him growing up. On how much it hurt to find out about Elliot betrayal, to find out Elliot only goal was to steal the Astral pulse, how he set up a trap that left him in a coma, him being tortured by the Red Ring at Elliot's order, and of course the attack on LA (Plus the final decision). And he's calling him Elliott the whole time.
And the end Z-Team is left there standing there. Realizing that while for them this is a cause for celebration, for Robert it's something completely different. They realize just how much someone that Robert at one point in his life completely trusted betrayed him. Especially the person you decided to cut and Visi.
