Ted was restless. With the magic gone, he didn't have much of a job with the wireless down. Running about the town delivering bad news was as useful as he could be. And what news. Ted liked to think himself a tolerant person, and he was sure his future self accepted Remus as his son-in-law regardless of his condition, but to see the consequences first hand was very difficult. Even worse, he felt helpless. No one knew where Remus was now, and Ted was sure Dora and Teddy were sick with worry, and his wife had to try and heal magical wounds with no magic... things were a mess, and Ted had no answers.
He'd taken to wandering to try and quell the anxiety, and found himself at the gym. He thought maybe a good workout might help, but when he entered, he found his nephew already there, beating the daylight out of the punching bag. "Looks like we had the same idea," Ted called out.
