[Amnesia]

Interesting that we see (for once) just how important E is to the process...and what happens when Ari is forced to stop leaning on E and get the job done himself!

I think you mean how unimportant E is. Ari managed to do a great job at salvaging the best possible outcome out of the situation that Walsh created. If E had been involved, I don't see how it would have turned out better.
