Billy & Weasel is a Potential Plotlines episode.


When Rosie goes to the Works for repairs, Weasel returns to Sodor and, as expected, causes trouble for the engines by destroying the oldest truck in Tidmouth Yards. But two days later, Billy has an accident when Edgar drips his oil on the track and the rear coach's back wheels come off the rails at the special points at Maron, so Weasel comes to the rescue. It seems that even Weasel has some good in him somewhere.
