If there was one thing that everyone knew about Dale Cooper, it would be that he has a big heart. Just look at the amount of people he's 'adopted' or how many he tries to help. So when Cooper heard that an area near him was having a pride parade, he jumped on the "Angstcendants" discord and shared the news. He invited everyone, especially his LGBT friends. He did let allies come along, especially Roy who wanted to be there in case something happened to his friends.

That's how he ended up where he was, curled up asleep in one of the dining chairs on the day of the parade. He'd let everyone come and stay at his house instead of getting motels and by the time he'd been content enough to go to bed, every piece of furniture in his home had been commandeered. Instead of waking anyone or anything, he walked over to the TV, which had been left on the history channel by Roy, and turned it off before doing a last check that everyone was still here and content. He did snap a few pictures, especially of the cuddle pile happening on his bed, before returning to the chair and falling asleep with his arms acting as a pillow on the table.

He hadn't awoken yet and his soft snores were muffled by his arms. Near his head lied a simple voice recorder, with the tape labeled 'Diane'; it was common for him to be seen speaking into it. When he did awaken, he would have an awful crick in his neck and back but he wouldn't care. Today was going to be a fantastic day and that's what mattered.
