Harry wasn’t worried about him, per se. He knew he was fine. It was just odd and slightly uncomfortable to go about his day without seeing Tom at all. Not that they spent all of their time together. Harry’s quidditch duties were quite onerous, and Tom had prefect responsibilities frequently. Outside of those instances, however, they were usually together, and Tom’s absence made Harry realize anew what a poor job he’d done making friends in this timeline. He missed Ron and Hermione, which made him sad, and even though it had only been two days he missed Tom, which made him feel pathetic and embarrassed, mainly because he knew Tom wouldn’t miss him the same way and he hated to be in such a lopsided friendship.
