But her plan goes awry when Brandon and his ex-wife Tanya agree to call a truce. PC Kerry Young is handing out invites to her wedding, but her ex-fiancé doesn't take it too well. Was he always this violent?

Simon Kitson comes to Cass Rickman's rescue when she gets into a tussle with suspected serial killer Shane Pellow, so as a thank you she invites him to the party. Later, after he sends a text message, she pulls out of the karaoke trio to meet him at a bar instead.
