As part of the 20th anniversary in October 2015, a number of long-running storylines reached a climax point. In particular, it features the exposure of the affair between Ste Hay and Harry Thompson (Parry Glasspool) to his father Tony and the other characters during a Hollyoaks Pride event. The underage sixth form student had begun questioning his sexuality following a kiss with John Paul McQueen, later developing strong feelings for Ste. The plot involving Diane O'Connor, Tony and Tegan Lomax regarding their children who had been switched at birth is also concluded. The week also features the departure of the Osborne family from the Dog in the Pond pub and they had moved to the Boarding House which was previously owned by (Dennis Savage). Another storyline featured was the reveal of the Gloved Hand Killer (the identity of whom had been a mystery to viewers since January). The killer has murdered five characters up to that point (Rick Spencer, Mariam Andrews, Will Savage, Phoebe McQueen and Dylan Jenkins), has had two failed attempts (Esther Bloom and Diane O'Connor) and killed another two during the week (Ashley Davidson, Dr. S'avage) before Lindsey Butterfield is revealed as the serial killer when she seemingly murders another regular character (Freddie Roscoe). However, he is later revealed to be alive. A month later, "Hollyoaks" aired (for the first time) a stillbirth storyline in which Mercedes loses her baby with Joe Roscoe (Ayden Callaghan).
