Dennis Stokes, played by Duncan Preston, plotted to con Fred Elliott with a Thai bride scheme. Dennis, met Fred at a golf club, and had a wife from the Far East, Lily.

However, unbeknownst to Fred, Dennis and Stacy are plotting together: Orchid is a false name used by Stacy. Fred provides the money for Orchid to fly over from Thailand, where he believes she lives. He meets Orchid at Manchester Airport, where she has been secretly waiting with Dennis. Fred then takes her to Weatherfield.

Orchid speaks in a Thai accent and claims to be staying with a distant relative in East Didsbury. Shortly after their first meeting, she says that she has to return home because her father is unwell. Dennis suggests to Fred that if Fred wants Orchid to stay, he could offer money for her father's medical bills. Fred later gives Orchid a cheque, and she says she will stay.

Harry Flagg, who works at Fred's business, The Rovers Return, follows Dennis, where he sees Dennis and Orchid (aka Stacy) talking together on the market. Harry notes that Stacy has a Mancunian accent.

In the meantime, however, Ashley has apologised to Orchid, and Fred proposes to her; she accepts. Despite this, Claire has her suspicions. Harry tells Ashley about what he saw on the market. This leads Ashley to take Fred to the market, where he sees Stacy and Dennis, and confronts them both. Fred threatens to call the police, but does not do this.

Fred subsequently returns to the market with Harry, and they find Dennis, who says that Stacy has gone to Ibiza. Harry pretends to be "ex-CID", and threatens to tell his former colleagues on the force about what has happened. To avoid this, Dennis hands over several hundreds of pounds in cash, and says he will provide more. Fred also makes Dennis agree to resign from the golf club. Dennis was not seen again.

Billy Platt is the son of Sarah Platt (Tina O'Brien) and Todd Grimshaw (Bruno Langley). Sarah, already a teenage mother, was 16 at the time she conceived Billy, after Todd had suggested the two try for a baby of their own. Sarah was reluctant, and when she discovered her pregnancy, she was considering getting an abortion, since her mother Gail Platt (Helen Worth) had recently had to deal with Sarah's stepfather Richard Hillman (Brian Capron) attempting to murder their family. However, Todd brought Sarah round to the idea of having the baby.

Just before Christmas 2003, Sarah's brother Nick Tilsley (Adam Rickitt), revealed to their mother that his sister was pregnant. By this time, Sarah had made a firm decision to keep the baby. Gail wanted Sarah to have an abortion, so she would not be 16 years old with two children; this caused friction with Gail. In April 2004, Sarah suffered her first placental abruption, and felt Billy was dead. Once at the hospital, it was discovered that Billy was fine, but his heartbeat was slow. This was caused by some uncertainty within Sarah and Todd's relationship.

However, when Todd reveals to Sarah that he is gay, she suffers a second placental abruption on 1 June 2004, three months away from her due date. The abruption was so serious that Billy had to be born by caesarean section. His first 24 hours alive were critical, and Todd was not allowed to see him, as Sarah did not want Todd to see Billy. In addition, Sarah did not want her son. On 2 June, Sarah finally agreed to see her son, who was in an incubator. However, Billy's health deteriorated, and whilst Sarah was bonding with Billy for the first time, he died.

Todd never saw his son alive, apart from a photograph that Gail gave him after his death. Although he was allowed to be named as the father, Gail and Sarah agreed that Billy should have Platt instead. Sarah then continuously blamed herself for his death until his funeral on 7 June 2004.

Despite doubts from the rest of the street's residents, Todd finally showed up with his family to say goodbye to his son. Sarah and Todd regularly visited his grave until they left Weatherfield.

In December 2015, when Sarah discovered she was pregnant with her deceased ex-boyfriend Callum Logan's (Sean Ward) baby, she tells Todd, whom she had reconciled with after her return in March that year, that she wants an abortion. However, Todd reminds Sarah of how she felt after Billy died, and suggests that this baby could possibly replace him.

Sarah later changes her mind after Kylie Platt (Paula Lane) stops her from making the decision, as she also reminds Sarah that her own son with Callum, Max Turner (Harry McDermott), does not remind her of him, and she loves him regardless. Sarah later gave birth to Harry in March via caesarean section, like Billy.
