There wasn't much chance that Jason was going to accept a bribe really, it just shows Robert yet again that you can't fix everything with money. Another character development for him.
I hope Aaron finds out that even though Robert paid money that it wasn't because he was buying Jason off because he didn't think Aaron was capable - he was doing it to protect him from getting into any more serious trouble through fighting. Another sign of Roberts love for his man.
Let's get these boys back together - they are wasted apart!
