I'm trying to think of a way to get Michael smoothly into the group without being ridiculous like:"Hey, I'm Michael" he said, inexplicably materialising from the air and pulling out a pair of sunglasses from his pocket. "I kill walkers with hatchets and eat cans of soup... And I'm all out of soup." he said putting on the sunglasses as a bald eagle flew over his head screeching.

Create a situation, run into some trouble and conveniently escape into the path of the others. Then that'll force them to retreat with you, giving you a nice warm opening to create some first impressions.
