Why was it that whenever he needed to urgently find something, his eyes would rake over the very thing he was looking for multiple times before he registered that it was right in front of him? Kyle realised, when looking all over the oven, that he was letting himself get too overwhelmed by the entire appliance, and had to consciously force himself to slow down, and look through one section at a time.

Inside the oven seemed as good a place as any to start with, and there weren't many places to hide something in there... unless you counted burying it in all the dirt and grime and general muck. Kyle, who was extremely glad that he had cast a Bubble-Head Charm on himself by this point, even cast a couple of quick cleaning charms on the inside of the oven, but found nothing.

Shutting the oven door, he looked instead at the dials, stared them all down, one at a time. Really, really looki--

Wait. No. Wait. That one. It was... it wasn't as filthy as everything else. It had been handled or... or something. Whatever it was, it clearly meant he was on the right track. Maybe.

Now there was just the problem of what to do with it. The riddle had essentially told him that turning the dial clockwise would give him nothing, and turning it the other way would... end in regret. So maybe he just needed to... pull it off? Or maybe the dial was the knot, and transfigured to look like something else, and he needed to undo it. Or maybe there was something else entirely that he needed to do that he hadn't even thought of.

Well, Kyle was nothing if not logical, and the logical thing here was to attempt the spell before he started pulling parts off of an appliance that likely ran on gas. If the spell didn't work, then nothing untoward would happen (nothing would happen at all, except that maybe if the dial was just magically concealing the item, that magic might be terminated) meaning that he could try those other avenues.

Raising his wand, Kyle pointed it at the dial.

"Finite."
