The fact that he mourned Kon like crazy, tried to bring him back, made his new Robin costume in "his colors", saw Prime when he got Scarecrow gassed, and he never stop missing him, leads me to believe that yes he might just listen to Kon because the minute he sees him a lot of that angst and dickery is going to dissipate.
But honestly the two people he would really listen to if they decided to come back from the dead would be Jack Drake or his stepmom.
