Romance with John Paul When Danny begins working at Hollyoaks High, he catches the eye of teacher John Paul, who is "delighted" that Danny seems to be attracted to him.
Hollyoaks producer
Bryan Kirkwood revealed that Danny's romance with John Paul would not only mean that John Paul would "get his share of the action", but also lead to "dark and unexpected consequences" for other characters. Billington told
Digital Spy that it was "really lovely" working with Sutton. This was not revealed to viewers before the airing of the episode, which saw Ste's partner
Doug Carter (
P. J. Brennan) phone Ste's father, who is revealed to be Danny. Roper's casting and Sam's introduction had not been announced beforehand as
Hollyoaks bosses wanted to surprise viewers. It was reported that Sam, who was billed as a "lioness" when it comes to her family, would be "prominent" character on the soap over the coming weeks as Danny "desperately" tries to juggle his "stable family life" and his secret relationship with John Paul. Kirkwood had decided to introduce Ste's family as he believed that Ste was "undoubtedly one of our most important characters" of the soap and was conscious that he was "languishing on his own" without a family. Their arrival brought more "family drama" for Danny due to a "shocking twist" where Tegan gives birth during her first appearance, having not known that she was pregnant. Danny admits that he wants a relationship with him again, but just as it "seems" that their affair is "back on", John Paul rushes to hospital after learning that his son
Matthew McQueen (Malachy and Connor Birchall) is unwell. In January 2014, Billington teased to
Digital Spy that John Paul and Danny's storyline was not "quite over" despite the characters having kept their distance from each other, and speculated that things could become difficult for Danny later in the year due to the possibility of Sam finding out about the affair, which Billington speculated would cause "severe ructions". The actor hoped that the Lomax family would stay together despite the ructions, as he got along well with the actresses of his female family, calling them "brilliant actors" and "such a joy to work with". He believed that Danny's inability to be faithful is his "main weaknesses", and that Danny does not believe his affairs impact his family life, explaining: "In an ideal world, it would always be a secret. He doesn't believe his relationships outside the marriage impact on it or the family. But his affair with JP is having an effect, because Danny loves him, which I don't think has happened before. He has had affairs, but he hasn't ever fallen in love with the person. He loves Sam and wants to be the one to explain things to her in his own words." Danny assumes that it is the homophobic bullying, which he knows about, and blames
Robbie Roscoe (
Charlie Wernham) about it, with Billington teasing that Danny could "have a go" at Robbie about it due to believing that he is completely to blame. The confrontation becomes physical when Danny loses his temper and warns Robbie that the truth will come out eventually. Billington believed that Danny thinks it is the "worst" that it is Peri that found, as she is the one who loves Danny unconditionally. When Peri confronts Danny over the "betrayal", their argument has an "unexpected outcome" when she falls down the stairs leading to the Lomax home, which Leela witnesses from a distance. Billington explained that Leela believes that Danny has given Peri a little shove but he has actually not, and he is "beside himself" and "absolutely horrified" that his "little girl" has been hurt. Billington teased that the affair would later be revealed to the whole family, and revealed that Danny would not be the one to confess to it. Danny is set up to look like he is talking anonymously online to
George Smith (
Steven Roberts) via a gay dating app. This leads to Danny's bisexuality being outed when
Sienna Blake (
Anna Passey) causes more drama for the family and messes with the sound board at the Hollyoaks High talent show, which leads to everyone – including the Lomax girls – hear Danny tell George he is bisexual when George confronts him backstage. Billington blamed Sienna for the situation, calling her "evil". Danny then ends up returning to his "cheating ways" when he meets up with George and, unable to resist temptation, shares a "shock kiss" with him.
Departure and aftermath It is later revealed that Danny is actually Peri's grandfather as she is the biological daughter of Leela and
Cameron Campbell (Cameron Moore). Later, in order to get Peri away from Cameron, Sam and Danny decide to emigrate to
New Zealand with Tegan and Peri, with Leela deciding to stay behind. Ste becomes hurt when he finds out that they are leaving without him. O'Donnell revealed that this shocks Peri, and makes her feel confused as she does not understand why she has been lied to her whole life. In the final moments of the episode that aired on 5 August 2014, Sam and Danny are involved in a "shock car crash", with their lives hanging in the balance after their car hits a van and flips over. The following episode confirmed that both Danny and Sam had died at the scene and Leela, Tegan and Ste are told the "tragic news" by the police. It is initially thought that Camera had hit them by accident, but in December 2015, it is revealed that Cameron targeted Danny and Sam deliberately, as he saw them driving and accelerated his car towards them. Camera drunkenly admits this to his brother
Lockie Campbell (Nick Rhys) and says, "That's what happens when you come between me and my daughter". ==Storylines==
