Bio
When Thomas got lost on his way to Bridlington Goods Yard, he met Theo and Lexi in an abandoned goods yard. They helped him get more coal and water, but unfortunately couldn't give him directions to Bridlington, because they didn't know the way either. Later on, after escaping from Hurricane and Frankie, Thomas met up with with Theo, Lexi and Merlin again. They helped him to feel better when he was sad.

When James was being held in the Steelworks, Theo, although unsure that he could do anything, helped Thomas, Merlin and Lexi to rescue him. After learning that Hurricane and Frankie revealed that they needed help at the Steelworks, Theo, Merlin and Lexi stayed behind to help them.
