Ending
At the end of series 3, CBBC viewers were asked to vote for a way to end the series. The choices were a "spooky", "happy", or "surprising" ending. On the premiere of the final episode, the "spooky" ending won the vote; on a later repeat of the episode, the vote was run again, but the "happy" ending was chosen.
- The "spooky" ending left the series on a cliffhanger, as a past Harry and Lucy encountered the future incarnations of themselves, who have returned from the future. Lucy is shocked at the sight of her past self. Realising that two separate versions of herself now exist in one timeline, the red-eye virus kicks in, and the series ends with the future of Lucy being uncertain.
- The "happy" ending was the same as the spooky ending, but the episode ended before the alternate versions of Harry and Lucy entered the room.
- The "surprise" ending has never aired, but creator Tim O'Mara has remarked that this ending would have revealed that Harry and Lucy, along with the rest of the group, were actually alien clones, and that the red-eye virus was a way of keeping the clones in check.
