Henrietta reminds Toby to fill up on coal, which makes him frustrated and forget to do so. He runs out at Crocks Scrap Yard, leaving him stuck with Reg. Edward sees him twice and Salty comes up with the idea that Toby is going to be scrapped. This is only supported by Reg lifting Toby up into the air to get their attention. The idea spreads and everyone believes Toby will soon be scrapped.

After he sees the Fat Controller's grandchildren with chickenpox, Henry worries about catching the disease himself. This feeling grows stronger after he sees Thomas, Paxton and Gordon with spots that he thinks are due to chickenpox.
