Michael really hadn't thought that he'd be able to make it to Merlin and Audrey's but his plans had fallen through at the last minute so he'd made his way there.
He knew he should knock on the door and wait for somebody to come let him in but he could hear the sounds coming from the backyard so he just made his way around the side of the house with a grin on his face, raising a hand in greeting when he saw Merlin and Gwen, not wanting to interrupt their conversation as he walked over to them.
