Dr. Grey always thought Doc was the insane one. In her opinion, any one counting as normal was boring. Or maybe it was just her crush instincts, always teasing Doc around.

She would love to chase Doc around, and Doc personally loved it a little. He liked showing off that Dr. Grey was chasing after him, and he felt rather flattered. Although, his teams took it the other way.

They were both doctors; a perfect match. Well... Kind of. Dr. Grey in all honestly was insane when it came to her hobbies and jobs. Like that one time she dislocated every part of a merc's body and put it back together. The things she does for Carolina!

Doc though, loved all of that. He loved her craziness, her smartness, just everything he could really ask for. It was good for O'Malley too.

In the end, both doctors fell in love in a weird way. It was insane.
