First thing is replace the hanger. With the newer RDs it makes it hard to visually eyeball straightness of the cage. If after replacing the hanger and you re-index Di2 shifting is messed up, you made need a new RD cage. At worst you need a wheel repair, an RD hanger, and a new RD. Killing an RD entirely is hard to do (sheering off the mounting bolt knuckle), and you probably only need a new cage at most.
I don 't think he has the newer group. He posted a pic about a month ago and I recall the cage was straight and not shaped like mine (R8070).
OP...Man really sorry to hear what happened. I would be sick to my stomach as well. How is the rest of the bike?
