Alastair's second vessel

Alastair's second vessel is the second major vessel of the demon Alastair.

Death Takes A Holiday
Following Sam Winchester's nearly successful attempt to exorcise him from his previous, brief vessel, Alastair possesses this man to go ahead with his plan to kill two Reapers in order to break one of the 66 Seals. Although Alastair succeeds in killing one, the Winchesters manage to save the other, Tessa, and Alastair and his vessel are captured by angels led by Castiel.

On The Head Of A Pin
Alastair, still possessing this man, is held in a devil's trap in an old warehouse in Cheyenne, Wyoming where the angels try to break him for information on how Lilith is killing their fellow angels. When that fails, they bring in Dean Winchester to use the knowledge of torture he got from Alastair to try to break him. Despite Dean's best efforts and doing severe damage to his vessel, Alastair doesn't break and escapes with the help of Uriel. Despite Castiel's best efforts, Alastair proves unable to be stopped until Sam arrives after finding them with the help of Ruby. Alastair breaks under the torture of Sam's powers and Sam then uses those powers to kill the demon and his vessel.
