 Describing the tone of the episode Ford describes it as " an all out romp " and an " action , <unk> ride " with " a lot of comedy in it as much as thrills and nasty monsters " . Davies stated that " the whole point of the episode is to have a right old laugh " . <unk> on the comedic aspects , something Ford considered whilst writing the episode was that " the trick is to have the comedy come out of the characters " rather than the scenario itself . It was Eve Myles ' idea to have Gwen <unk> eat <unk> after waking up pregnant ; the script had only specified the character drinking a glass of water . The episode also plays on Gwen 's conflicted feelings between Jack and Rhys . Davies felt it would be " irresistible " to have the wedding temporarily halted by " the one man Rhys doesn 't want to see running down the aisle . " Ford stated that whilst Jack is " the series hero " Rhys is " the hero of this episode " . He compares a sequence where Rhys arms himself with a <unk> to defend Gwen to the character being in " Evil Dead mode " . Producer Richard Stokes commented that the episode illuminated that " even though [ Gwen ] ' s put [ Rhys ] through some really difficult times , she really does love him and want to be with him . " In an early draft of the script Gwen and Rhys had their memories wiped at the end of the episode in addition to the other guests and were convinced by Jack that the wedding had been problem free .
