Seeing is Believing


 * (Fade to Thomas is puffing through the countryside. After he passes the tree bushes, Merlin appears, whistling and Thomas startles)
 * Merlin: Hello again, Thomas. Had any big adventures lately? I've...
 * (While Merlin speaks, Thomas laughs, and before Merlin can finish, they hear a loud whistle sound is heard in the distance)
 * Thomas: Huh?
 * (It is only Trevor who has a brand new steam whistle, he pulls up beside Thomas and Merlin. Thomas is very pleased, but Merlin is shocked)
 * Trevor: Hello, Thomas!
 * Merlin: (gasps) How did you get off the tracks?! Have you been derailed?
 * Trevor: (to Merlin) No, I don't need rails, I'm a traction engine. (to Thomas) What do you think of my new steam whistle?
 * (Trevor blows his new steam whistle loudly. Unknown to him, Thomas and Merlin, a squirrel is seen on the tree branch and is just about to eat the apple, but it frightens him away, and that's what animals do not like steam engines' loud whistle)
 * Thomas: Oh! (laughs) It makes you sound like a big railway engine!
 * Merlin: How fantastic! I'm an Experimental Engine. Want to see what I can do? Invisibility on!
 * (Merlin closes his eyes and steam appears around him. Trevor is shocked and puzzled when he see this, but Thomas only chuckles)
 * Thomas: This is Merlin, Trevor! My friend from the Mainland.
 * Merlin: And I'm the best hider ever.
 * (Trevor smiles)
 * Trevor: Oh, hello, Merlin! Very nice to see you! (laughs)
