When Academy student Rasmee bursts through Tilly's door clutching a trembling map, the morning calm of Fennbridge shatters like glass. Her cartography thesis has gone magnificently wrong—creating a map that shows three different versions of the town layered over each other, all somehow true at once. Now residents are walking in circles, ending up where they started from impossible directions, and even Marge the cat is walking away from this particular problem.

As the town begins to fold in on itself, Tilly finds herself reaching for Hazel's repair books and discovering what it really means to be a bookbinder. Some problems can't be solved by one person alone—they require two sets of hands, the right thread, and someone brave enough to make a promise about which version of reality deserves to be real. But when your map shows three possible futures, choosing just one means letting the others go forever.

In this episode:

- Rasmee's ambitious thesis creates a temporal cartographic disaster

- Tilly discovers Hazel's book "For When You've Done Something Daft"

- A lesson in the difference between truth and promises

- The delicate art of unpicking reality, one stitch at a time
