Branch and Tick

Branch went first, because Branch's whole discipline was refusing the first easy answer. For every clue, ask: what else could explain this? Branch would not let one obvious story stand until every live rival had been checked — this is reasoning to the best explanation, and it fails the instant there's only one explanation in the running. "The pawprint means the cat was here," Branch agreed. "But does it mean the cat ate the cookies? Those are two different claims, and we've quietly merged them. Let's separate what we see from what we're assuming." And Branch laid out the branches, unhurried, one at a time. Branch one: the cat ate the cookies. Branch two: the cat came in after the cookies were already gone, and the empty tin and the print are two unrelated facts that happen to sit near each other — a coincidence we're mistaking for a cause. Branch three: someone ate the cookies, opened the window to frame the cat, and the cat wandered in later. Branch four: there were never cookies in that tin today at all. "Four explanations. All fit what we can see. That's the trap — the obvious one isn't wrong for being obvious, but it isn't right for coming first. Each branch gets tested before we trust any."

This was where Tick stepped in, because the way to test a branch is against the clock. Tick's discipline: put every event in order; the sequence rules out the impossible. So Tick pinned each known fact to a time. The cookies were counted full at three — Grandpa saw them. The window was found open at five. The mud outside stayed dry until the four o'clock rain, so the print could not exist before four. And the cat had been shut in the sunroom, everyone agreed, from three until half past four. "There," said Tick, laying it in order. "Now watch what the timeline does to Branch's four stories. I'm not going to argue anyone guilty — I'm going to let the clock delete whatever it makes impossible."

So together they walked each branch across the timeline, and one by one the clock knocked them down. Branch one — the cat ate the cookies. But the cat was locked up until 4:30, the print couldn't exist before the 4:00 rain, and — most telling — Grandpa's own note said the tin was already empty at 4:15, before the cat was ever loose. "The cat can't have," said Tick. "It wasn't even out. The clock says no." Branch one fell. Branch two and four fell on checking too — the tin had been full at three, and the print was real, so neither the coincidence nor the no-cookies story held. But Branch three — someone ate the cookies before 4:15, then opened the window — survived. It broke no clock; it fit every time. And then a small quiet clue clicked in: chocolate on the little brother's sleeve, from before lunch. "There it is," said Branch softly. "The one explanation that survives both filters — the alternatives and the timeline. Not the loud first answer. The one still standing after every test." The cat, entirely innocent, washed its paw.
