Indeed, Jeffster singing Mr. Roboto was completely awesome.
This series better get a 3rd season, they cannot leave us hanging now that Chuck is kicking major ass. That final scene was pretty cool... some Bruce Lee type of shit.
Orion had an Intersect in his head all along, we should've known. Bryce is dead, kinda sucks... but he did survive the last time, so he might not be dead yet.
