Also the Finch flashback stuff wasn't really what I was expecting. Seemed like it was all character development stuff (showing us why Finch has done what he did over the years). Was kinda hoping to see what he did that lead to him changing his identity. Perhaps there will be more in the future.
he talks about it in the episode where substitutes teach(pi r square or whatever)
as for root, a few episodes ago(ibelieve part 1 of the threeparter) root did something to get rid of the cage's ability to block transmissions
