The Relationship Between Sablear and Benson

Sablear and Benson are trying to find some connection between these two guys. Huang's like, okay, but you're assuming the attacker isn't delusional. Something could have set this guy off. So they head over to Gammon's place to ask why the two men went over there to yell at him. And then they show the receipts and he cops to knowing them when he's pushed against a corner. He says they were having a business discussion. They also find out that they've all been working together for 10 years.
