The most overlooked character is the Doc. He has kept Wick alive during all the mayhem. I hope this is how Wick 5 opens with the Doc saving Wick & handing him a marker, then prequels.

I see wick coming back like this. The doc is asking john if he wants to live to see his orphaned child as he works on his wounds on a airplane. Simple and to the point and ties everything together.
