Two Minutes to Midnight
Supernatural Season 5 Episode 21 (05/06/10)
It's safe to say A LOT goes down this week: Crowley makes Bobby an offer: the location of Death in exchange for his soul. Bobby actually agrees.
Elsewhere, Sam and Dean confront Pestilence, who unleashes a deadly virus upon them. As a result, Castiel intervenes on their behalf. Later on, Dean meets with Death to chat about Lucifer - and an unholy alliance is formed.
