There's a nanosecond of flashing anger in Raphael's eyes. Raphael was doing what he hadn't done in hundreds of years - take action in looking after humans. He was starting to enjoy it, point of fact - seeing them safe at home, safe from the decay and monsters, snapping tendons of caregivers who raised hands against children in their care. And he didn't take orders from anyone who wasn't Michael.

And it was Michael's order that made him back down - more than fear.

A second longer, chin held high in defiance, before he spread his wings and flew off.

Back to Michael's side, wherever he was.
