As they pursue estate agent Adam Armstrong who accidentally killed a homeless man by shoving him, Rachel confesses to Janet that she had sex with a stranger the night before and that she bitterly regrets marrying Sean. When Dominic killed Nick Rachel was implicated and, though exonerated, had to face a tribunal where Gill spoke up for her. Rachel was feeling down at the time and to marry Sean seemed to the right thing to do as he had been so kind to her. Recollections of the wedding are not happy for either woman as Rachel's estranged mother Sharon turned up and got embarrassingly drunk at the reception, where Adrian also suggested to Janet that they split up.
