Michael (A Change is Gonna Come)

Michael is a kid who convinced Izzie to treat a deer that had been injured.

History
Michael and his father, Chris, came into the ER. Chris had an arm with him, Nancy Walters' arm. Michael was shouting about a "she" who was bleeding in their truck. The doctors grabbed supplies and ran out to the truck only to discover that the "she" was a deer. Despite Chris's insistence that Michael didn't need them to do pretend medicine on the deer, Izzie and her interns jumped in to save the deer.

They were able to save the deer and an animal rescue came and took the deer away.

Familial
His dad thinks he needs to grow up and learn to face things.
