During Riley's stag do his brother Seth believes he has killed a stripper. Miles Higson who plays him told Digital Spys Daniel Kilkelly that the storyline would be a "really difficult time for Seth" which would make him contemplate suicide and push him "really close to the edge". It was revealed that Jeff Rawle who portrays Silas Blissett would feature in the series. Series producer, Emma Smithwick, later confirmed that the series would feature the death of a regular character at the hands of Silas. Viewers were led to believe Theresa would become Silas' next victim when a leaked clip of Silas preparing to attack Theresa was posted on YouTube. Alice Barlow, who portrays Rae Wilson quit her role in early 2011 which prompted producers to begin devising a memorable exit for the character. Barlow's exit was not announced so the audience were surprised when, in the concluding episode of Hollyoaks Later, Rae is brutally murdered by Silas.
