This came to me whilst creating Lindefarne's Birthday piece;
as I soon realised that Turvy had made her debut long before 2017 in some of the earlier comics. I know Bill said he always thought of his comics 2 months ahead, but 20 years in advance?
(Okay, the 2001 prediction is a result of gluttony rather than pregnancy, but it still looks like Lindesfarne's pregnant)
Though, Turvy does also bring in a continuity error from this 2001 Valentines Day story, that shows Lindesfarne with hedgehog grandkids. Now here, one of two things might've happened;
1. Turvy actually had pure hedgehog babies (but is it possible for a hybrid to have normal babies?) 2. Turvy adopted the hedgehog children, possibly as a means of preserving the species like the Channel 5 programme "Saving Britain's Hedgehogs" hosted by Steve Backshall, which claimed that the British Hedgehog might be extinct by 2025.
All in all, none of these maybe canon, and might not lead to anything, but still, one fault against 4 foreshadowing scenes could still have a surprising results in the near future...
