 Question: can you have a heart attack from laughing Context: Azazel's last appearance chronologically is in the second season finale ``All Hell Breaks Loose'', where he kidnaps Sam and the other young adults that he had infected. He visits Sam in a dream, and reveals that his ``special children'' must fight to the death to determine who will lead his army. Although Sam is the demon's favorite, the super-strong Jake Talley becomes the winner. As Dean sells his soul to another demon in exchange for Sam's resurrection, Azazel gives Jake the Colt and coerces him to travel to a cemetery in the middle of a giant devil's trap. Though Sam and Dean, along with other hunters, attempt to stop him, Jake uses the Colt as a key to unlock a mausoleum there. This action briefly opens a gateway to Hell, releasing Lilith and hundreds of other demons. With the devil's trap around the cemetery now broken, Azazel confronts the Winchesters and easily overpowers them. However, John's soul escapes through the Gate, and distracts Azazel long enough for Dean to shoot him dead with the Colt.

Brown's party of 22 was defeated by a company of U.S. Marines, led by First Lieutenant Israel Greene. Colonel Robert E. Lee was in overall command of the operation to retake the arsenal. John Brown had originally asked Harriet Tubman and Frederick Douglass, both of whom he had met in his transformative years as an abolitionist in Springfield, Massachusetts, to join him in his raid, but Tubman was prevented by illness, and Douglass declined, as he believed Brown's plan would fail.
