A Friend in Need

"Spot on, Jack! You'd make a mother proud!" "And a tank engine grateful!"

- Miss Jenny and Thomas praising Jack

A Friend in Need is the eighth episode of the sixth season.

Plot
Thomas is taking some trucks along the line, and is pleased to know that he will see his new friend Jack when crossing the Quarry Bridge, as this is where the pack are working. Jack has learned his lesson from the quarry experience and when he stops himself from jumping in again, Alfie and Isobella congratulate him. However, when Ned the clumsy steam shovel knocks the keystone out of a bridge, it begins to fall as Thomas approaches it. Unable to stop, Thomas rolls onto the bridge. Luckily, Jack jumps in and holds the bridge up with his scoop until Thomas can reverse to safety. Kelly rushes to Jack's aid, but Jack can't hold the bridge, and it collapses before Kelly can help. Jack has bent his arms, and is very worried what Miss Jenny will say, but she is pleased with Jack's bravery and accepts Jack into the Pack. Jack then goes to get his arms repaired.

Goofs

 * When Jack and Alfie load Max, Max's right-rear wheel spins around. It spins again in the close-up of Jack loading dirt into Max.
 * When Ned clears the bridge, his smokestack is missing. It may have been removed so Ned's model could go under the bridge.
 * In the shot of Jack emerging from under the bridge, the studio is reflected in his front window and the ground he travels over bounces up and down.
 * In between the shot of Jack's face turning from happy to sad, Jack's roof shifts slightly to the right.
 * When Ned says "Sorry", his eyes are wonky.
 * In the shot before Ned knocks the first keystone away, his crane arm goes under the bridge without causing any damage.
