Supernatural Season Finale Clip: Dean Backs Sam
Someone is about to die on the season finale of Supernatural.
Meanwhile, as producer Sera Gamble put it:
"Sam comes up with an incredibly risky Hail Mary to defeat Lucifer, which involves spending some very creepy, violent one-on-one time with the guy."
It also involves Dean getting on board with his brother's seemingly crazy plan. Watch their interaction below, courtesy of Thursday's episode, "Swan Song."
