They regret nothing, from the first conversation where they argue over the name of their first child, to deciding who gets to play bad dad to punish Miranda when she sneaks out of the house.
They snark, grump, and love one another with the same abandon that they had before they met, before their lives truly began. They are older now, but just the same as when they were two young men dreaming together.
They have raised three children, watched Dom go to be with Mal, and know that if they had to do it again, they would, changing nothing.
