Billy Mayhew William " Billy " Mayhew is the vicar at St . Mary ' s Church . He is the ex - boyfriend of Sean Tully and currently in an off / on relationship with Todd Grimshaw . Biography . Billy met Sean Tully at a nightclub in December 2014 . The pair got chatting and exchanged numbers . One week later , Sean invited him to 11 Coronation Street for dinner and to meet Eileen Grimshaw , her son Todd and Eileen ' s half - sister Julie Carp . In April 2015 , Billy and Sean went for a hike in the Peak District , after a mere four mile walk they decided to stop at a local pub for a meal and somewhere to spend the night . At the pub they were offered choices from the limited menu , one of which was hotpot and Billy enjoyed ribbing Sean that the pub ' s might be better than the one he served in the Rovers cooked to Betty Williams ' s handed - down recipe . They also asked the Landlord for a room for the night and were told that the only one available was a twin . Sean ' s comment to Billy about pushing the two beds together caused the landlord to give them a significant look as he asked for their names for the booking . After the pair finished their meal , the landlord told them that he actually didn ' t have any rooms left and gave the excuse that his wife had taken a phone booking that morning , but followed her usual habit of not writing it in the book . Sean and Billy smelled a rat and questioned the response but were told that he didn ' t have to explain himself . He added insult by injury by telling them that they could have their puddings but then they had to leave . Sean confronted the man with his bigotry by quoting the old boarding house notice of " No blacks , no gays , no Irish " and told him to get into the twenty - first century . Billy also questioned if the man ' s stance was Christian but was told that he hated " God - botherers " more than he hated . . . but couldn ' t bring himself to finish the sentence . The pair accused him of cowardice as well as bigotry and left the pub . After the fiasco Julie informed the " Weatherfield Gazette " about the homophobic incident that had occurred . The following month , Billy conducted Deirdre Barlow ' s funeral . Billy ' s big break in Weatherfield came in January 2016 , when Eva Price informed him that she was skeptical that her boss Aidan Connor ' s new business partners , Richie and Julia O ' Driscoll , were keeping Marta Zarek , a Polish worker , as a slave in their home . Billy couldn ' t be too sure , so he and Eva went hunting for Marta when she was found to be hiding in the Underworld supply loft . Billy and Eva found Marta under an overpass , and they tried to question her on what was happening , but she ran off . Eva later got critical evidence that the O ' Driscolls really were keeping Marta prisoner when they were acting secretive about their private life . This convinced Eva to organise breaking into the house and seeing if Marta really was being held as a slave . On an initial stakeout , Billy and Eva saw a figure who looked like Marta through a window , even though the O ' Driscolls had told them that Marta had gone back to Poland . The next day , Aidan was convinced that the O ' Driscolls really were holding a slave worker captive , and agreed to help Billy and Eva . The pair broke in to the O ' Driscolls ' house as they were at a convention , and they found a door with a padlock on it . After searching , the pair found a key , unlocked the door , and found a cowering Marta , hunched in fear . They promised to help her , but Richie and Julia arrived home early from the convention , trapping the trio upstairs . They found Billy , Eva , and Marta , with Richie punching Billy , and holding Marta over a railing . Billy and Eva ' s saving grace came when Aidan arrived just in time and right - hooked Richie . Aidan had rushed over as Eva was not answering her phone , which had fallen out of her pocket in the car . Billy called the police , but they arrested all of them ( excluding Marta ) for various reasons , Richie and Julia for slavery , Aidan for assault , and Billy and Eva for burglary and criminal damage . Later however , Billy , Eva , and Aidan were all free to go , and Marta went back to Poland . In July 2016 Billy began developing feelings for Todd Grimshaw . He broke off with Sean , and embarked in a love affair with Todd . Quotes . " I ' ve been here three weeks , this is my first time in the village " ( First line , to Sean Tully )
