Sure he has his own path like many others in the game, they're all side characters except for Sophia & Dylan, or even Ellie I would add to that because we had to make a choice for her as well (to forgive Logan or not), we have to make choices as Dylan and play as him sometimes, all we get from S@M is "oh" "I love you Mrs. Parker" "Yes I will help with the groceries Mrs Parker" "Can I taste your nipples Mrs parker"... side character that has his own path, Aiden is also a side character but he has a much bigger impact in the game than S@M does, and that to me makes S@M nothing more than a side character that the player can play if the player chooses to play his path.
