Kate Bishop and Open!
Kate wasn't thinking about her birthday. She wasn't thinking about spending the day or the night alone. She wasn't thinking about Billy and Teddy and Cassie and Tommy and Noh-Varr and America... Okay, she was thinking about all those things. She'd been thinking about all of them as she put on her tight skirt, perfected her hair and makeup, and headed out to go to Thor's New Year's Eve gathering. She was thinking about being alone more than anything else. Sure, Clint was around. But he was Clint. Besides, he was busy with Jamie so much. Kate needed to start making her own friends.
She wandered into the bar and realized this was very much not her scene. Then she hit the VIP room and decided the dance floor? That was her scene. Dancing until she was exhausted and sweaty? That was her scene. She wanted to dance until her feet fell off and she crashed. So she started, moving through the people to dance in the middle of the floor.
