On the season six DVD, an alternate ending to "Alpha" is included. In this version, Mulder receives Berquist's "I Want to Believe" poster and hangs it on his wall. The scene then cuts to Officer Cahn who is recuperating in a hospital bed. When the attending nurse closes the curtains around him, his eyes flash red, insinuating that he now possesses the Wanshang Dhole's morphing abilities.
