- “Well, they've mended me tubes, but they didn't even look at me brakes! Me gauges! Me squeaky wheels..."
"All in good time, Henry.”
- ―Henry and Emily
What's the Matter with Henry? is the sixth episode of the seventh season.
It is the end of another busy day and all of the engines are happy, except Henry who is feeling ill once again. He complains that his boiler is grumbling. Thomas teases him about it, but Henry crossly moans that Thomas does not care and leaves. Emily notices a puddle of water where Henry was standing.
The next morning, the Fat Controller tells Henry, Thomas and Percy to collect coal trucks and take them to the docks. The two tank engines puff away quickly, but Henry is still feeling ill. Despite this, really useful engines do not complain, so this time, he tries to move anyway, worried that the Fat Controller may not care if he is ill again.
Henry is still leaving a trail of water behind him as he puffs along, which worries Emily even more. Percy and Thomas continue to tease Henry, thinking he is just being lazy. When they arrive at the coaling plant before Henry, they make a plan. Thomas fibs to the manager that Henry wants to take lots of trucks. The manager agrees. Meanwhile Emily tells the Fat Controller about Henry's problem and he sends her to find him.
Henry arrives at the coaling plant and is horrified to see a long line of trucks left by Thomas and Percy. But he still has to take them, so he sets off and pulls with all his might. However, the trucks prove too much and Henry grinds to a halt in the middle of the line. Emily pulls up alongside and sees that Henry needs help. So she changes tracks and couples up to Henry while his driver uncouples the trucks. They set off towards the docks.
When they arrive, the Fat Controller praises Emily and tells Henry that he was brave for taking the trucks despite being ill. Thomas and Percy are ashamed and apologise to Henry for not believing he was sick. The Fat Controller sends Thomas and Percy to pick up Henry's train.
Soon Henry's mended and back at work, but he grieves to Emily that the workmen did not look at his brakes, gauges, or squeaky wheels. Emily just laughs and assures him that everything will be fixed in time.
