- In order to get Dizzy to keep helping her get to MK, Sarah confesses that they're clones, though she doesn't necessarily tell him everything.
- Irony: Ferdinand brags to Siobhan that he and Rachel can retire somewhere in the lap of luxury. By the end of the episode MK leaves him completely broke.
