Harry couldn't remember finding any adult so impossibly adorable as he did Jack when the tall wizard showed up wearing a skunk cap. He had a hard time not laughing, but didn't waste any time in stealing the cap off Jack's head. He'd put it on his own head but it had disappeared by the time the movie started.
"Love the hair," He murmured into Jack's ear, leaning over a bit farther than necessary to whisper. He could tell Teddy loved it too from the way the little boy kept peering up at Jack, grinning widely. He even offered the artist a cheerio, which Harry knew was a huge compliment in Teddy-world.
Harry was oblivious to the rest of the world as the movie played, unconsciously leaning against Jack a bit. He wanted nothing more than to be curled up together watching it, with no one else there to interrupt them. Merlin, he felt like a school girl! He grinned at himself, reminding himself several times throughout the movie that Jack would be staying for dinner later. When it would just be them. He grinned at that thought.
