Valve has sent over a new trailer for Portal 2 (you know how much we love those), this time highlighting the vocal talents of The Office scribe Steven Merchant in the role of Wheatley. Merchant's a wonderful match for the spherical sidekick, who's sure to win you over with his unpoised, upbeat blathering.

Just think of how sad you'll be when you inevitably drop him into a pit of fire.
