Damien Lennon, nicknamed Damo, is a fellow priest who is an idol of Dougal McGuire. He is quite rebellious as he smokes, loves football, as well as the British group Oasis (he openly hates Blur) and convinces the latter to get an earring (much to Ted's anger). He is the real culprit behind the theft of Mr. Benson's whistle but gives it to Dougal to keep safe for him. He is forced to confess to the theft by his housemate Father Frost.
He is also seen as a passenger to Dougal's left-hand side on the priests' flight from hell.
