Butcher simply as Billy, while Butcher addresses Cassidy simply as Proinsias. After Butcher's Scottish protégé "Wee Hughie" Campbell arrives in the bar from his undercover assignment with the G-Men, and hears Cassidy can write "fuck off" in the head of a pint of Guinness, he orders such a drink before discussing his assignment with Butcher. As the two leave, Cassidy silently closes up his bar, smiling. Television series Preacher (2016–2019) In the 2016–2019 AMC television series adaptation, Joe Gilgun portrays the character. Unlike the comic series, Cassidy usually appears without his trademark sunglasses, and has normal eyes. Season One (2016) In the first season, working in a corporate jet as a flight attendant, Proinsias Cassidy drinks with a group of hedge funders while telling them his last trip to Tijuana. After discovering a Bible in the bathroom, whose pages are covered in thick notes scrawled all over them, Cassidy notes via the angles of the outside of the plane that is not flying toward Tijuana. He then kills the hedge funders and pilots, who turn out to be assassins there to kill him. Cassidy reveals himself a vampire by drinking the pilot's blood and jumping out of the soon-to-crash plane (the assassins having been vampire hunters) with a to-go bottle of blood and umbrella in hand. Cassidy, whose guts lie around him in a crater in a nearby cornfield, protected from the sunlight by the shadow of a cow, lures said cow in and devours it, regenerating his flesh. That night, Cassidy goes to local bar to contact his sponsor on the phone as to what he should do next, in the process befriending local preacher Jesse Custer. Impressed by witnessing Jesse beat up who he believes to be the abusive husband of one of his churchgoers (due to the husband's son mistaking his parents' BDSM activities for abuse) and his friends, before joining him in a jail cell overnight after being mistaken by local Sheriff Root for Jesse's accomplice, the two men shake hands after Jesse is released on bail before parting ways. Three days after Jesse is then possessed by Genesis (the offspring of an angel and demon whose powers rival that of God), he learns that Cassidy had found him passed out at the church and has since moved into the attic, carrying out basic maintenance on the church itself, caring for him during his recovery.
