Later on, Tex is still being rude to George and Theodore when a storm begins to brew, and the tugs decided to check on Tex's anchor cables. Afterwards, Theodore tells the tugs that Tex is a bunch of rods and rails, and George starts to think Theodore and Tex are friends, which upsets Theodore. When the storm hits, Tex's cables snap and George is sent to stop him from running into Benjamin Bridge, but after some choppy tugging, George gets caught and calls for Theodore.

 * "Hank and the Silly Faces": When Hank first meets Millie the Fishing Trawler, he thinks she is just making silly faces.

Instead of rejecting her, the tugs take the trawler to the repair dock. She worries that no one will be able to fix her, but just as her new friends predicted, the repair is simple. She tells the tugs that seeing with her new glasses is 'just like making friends with the world all over again.'

Emily just gets mad and hides. In the process of looking for her friend, Carla gets lost, and then gets stuck. The tugs realize that if they had confronted Carla about being bossy in the first place, the cruiser probably wouldn't have gotten lost. They know that they should speak up next time. Carla, on the other hand, hadn't learned anything about being bossy. When the tugs find her, she still insists on giving orders, but when her instructions undermine the tugs' efforts to free her, she finally realizes that sometimes it is better for people to do things their own way.
 * "Hank's Cozy Cove": The tugs must bunk in a strange cove while their dock is being dredged, and everyone is having trouble falling asleep. Everyone but Hank, that is.

He looks everywhere, even places he hadn't visited that day. It finally occurs to him to ask his friends if anyone has seen the siren. Sure enough, Emma Sophia, who he had helped dock earlier, had found it. Theodore is happy to have the siren back, and is tempted to sound it, but that might make others think he is in trouble, which is untrue because he's found his siren.
 * "Theodore Takes Charge": Theodore is not sure how to be in charge of the harbour clean-up without losing his friends. He is afraid they'll be mad if he gives orders, so he just keeps quiet. When nothing gets done, Theodore concludes that he just isn't good at being in charge, but the Dispatcher explains that people expect a tug in charge to be clear about what needs to be done. When Theodore takes the Dispatcher's advice, he discovers that true friends follow a true leader.
 * "George Waits His Turn": George never wants to wait his turn. Most of the time it is just annoying, but when Emily, Theodore, and George are sent to turn an iceberg away from the harbour, George's impatience nearly results in disaster. His first reaction is to blame Emily, but he knows it is really his own fault. That night at story time, George struggles to wait his turn to tell about the iceberg adventure. Emily smiles and lets him go first. She knows that George has learned his lesson.
 * "Hank Floats Forward": Hank is so excited that he is finally allowed to move ships by himself, that he doesn't pay attention when he helps Digby off of Willy's Island. He gives the old cable ship a good scrape on the sharp rocks. Digby is upset and tells everyone that Hank isn't good at moving big ships. To help Hank restore his reputation, Theodore brings him along on his next job and puts the little tug in charge. With Theodore's encouragement, Hank does a good job with everyone watching, and even Digby has to admit that Hank might be a good tugboat after all.
