1989-2015: Childhood loses and discovering her sexuality
Born in November 1989, Kate was Johnny and Louisa's second child - following her brother Aidan's birth six years earlier. However, unbeknownst to everyone Johnny had fathered another child, Carla, in 1975 after having an affair with Sharon Donovan. While growing up in Manchester, Kate was close to her distant cousins Paul, Liam and Michelle - and Johnny became fearful that his lies would be exposed when Paul ventured into a relationship with Carla.
In December 1993, Louisa discovered the truth about Johnny's betrayal after Sharon confessed everything to her. She planned to leave him, and take both Aidan and Kate with her, but was tragically stuck by a car and killed before she had a chance to do so. Now more desperate than ever to cover up his lies - Johnny tried to persuaded his second cousin Barry Connor to move back to Ireland, in the hopes that he would take his children and Carla with him. However, when Barry and his wife Helen finally decided to leave England none of his children agreed to go with him so Johnny moved to another part of Manchester along with Aidan and Kate.
At some point, Kate became a holiday rep and began to experiment with women while abroad - realising that she was a lesbian, Kate came out to her father who was initially unhappy with the revelation but eventually warmed to the idea as he just wanted her to be happy. Kate entered a long-term relationship with Caz Hammond and the pair became engaged, however due to her being in the army the pair often didn't see each other for long periods of time.
2015-2016: Dealing with her father's lies
In late 2015, Johnny put £100,000 into Aidan's bank account as a tax dodge - and, at the request of Nick Tilsley, Aidan invested the full amount into a 40% share of Underworld, having discovered that Carla was going through financial difficulties. Johnny and Kate tracked down Aidan to Weatherfield and were shocked to discover his investment.
Johnny eventually agreed to stay and help run Underworld, leaving Kate to take up a job in the packing department. Kate was later forced to reveal her sexuality, after her colleague Kirk's wife Beth Sutherland accused her of flirting with him. Befriending fellow lesbian Sophie Webster, Kate shared a kiss with her as she was feeling lonely in Caz's absence - however, the kiss was interrupted by Caz's impromptu return. Kate put the blame on Sophie in order to save her relationship with Caz.
Later that year, in December 2015, Carla's half-brother Rob Donovan began trying to cause trouble for the Connors from behind bars (after having been locked up for the murder of Tina McIntyre). Rob attempted to blackmail Johnny telling him that he knew that he was Carla's real father. Johnny paid Rob £10,000 to keep quiet but this was not enough and Rob continued to blackmail him, knowing there was no way to win with Rob.
Johnny revealed the truth to Carla himself who then in turn told Aidan and Kate.
Kate broke up her engagement with Caz and later dated Imogen Pascoe for a few weeks. During her relationship with Imogen, her friend Rana Nazir, developed strong feelings for her to which she confessed after Kate and Imogen broke up.
After having an affair for a few months and confessing to Zeedan - they are currently in a secret relationship due to Rana's family paying Zeedan to stay married to Rana for a year, which Rana guiltily agreed to.
