The ending for BK in season 4 was pretty awesome, but I really loves some of their scenes is season 6
I was hoping it would end wth Beecher being out of prison.. of course the Aryans and Schillinger would get what was coming to them
But yeah I wanted Beecher to be set free and for Keller to love him the safe way and finally let him go
I think that would have been growth for Keller and Beecher could finally be with his children.. both still loving each other of course, but just knowing that it wasn't meant to be
