Considering it is up to the writers and the actors, we would have lost Rose no matter what we would have like 9 to do, but- in my mind I like to think he would have gone get her.
I am not sure you heard saw the rumors/ trailers for season 4.
If there was a way to get her back, I think he would have done with out hesitations, weather 10, didn`t and cope with the lost.
