I’d like to point out that while Oliver seems to have jumped to the conclusion that the witness is a current member of the team other than his best friend or his wife, there are many more contenders. The witness could theoretically be Roy, the bandages dude, Vince the vigilante, a reanimated Malcolm Merlyn, the Russians, Quentin, Lyla, or anyone named al-Ghul.

Of course Rene soon fesses up, but not before Oliver reveals that the OG 3 have been spying on the new kids. With every new member of the team there has been some sort of transition period, but with this group (as well as the two members they have since lost) that seems to be a rougher and longer transition. Evelyn’s betrayal, mentioned frequently here, certainly contributed to that. But there’s also more distance between the original team and this crop of newbies because Roy, Thea, Sara, and Laurel all came and went. That makes them two generations removed, a gap Oliver has never fully closed, nor does he seem to want to.

Oliver’s poor judgment, aided and abetted by Felicity and Diggle respectively, drives Dinah to quit the team and reunite with Vince. Rene is gone, and Curtis’s departure seems to hit hardest. That may be because he’s been with them the longest, but it could also be due to the level-headed way he notifies them. The original team can pretend they’re right with the other two, but there’s no justifying how they drove Curtis away.

I can’t help but feel happy for Rene and Curtis, in particular. Curtis clearly needs some time to think over his priorities in life, and spending less time with Felicity might help him gain some perspective and stick up for himself more when she walks all over him. And Rene has a good job and his daughter back, and as we’ve seen with Dig and Ollie, having a kid makes a person question their place in the vigilante business.

I doubt this breakup of the team is for long, but it honestly seems like a healthy choice for everyone except Dinah, who is spending time with her murderous ex. Watching Dinah and Oliver go toe to toe is some of the best chemistry this season, since they’re so similar in temperament. But it’s Diggle who usually spends time with her and therefore truly betrayed her, and that relationship won’t be easily repaired.
