You and this alligator had a great bond. You didn't know it was possible, but this alligator didn't eat you. It loved you. So when you joined the Van Der Linde gang, you had to leave the alligator. But right now, you were doing a mission at that same swamp with that alligator with Arthur.

And you saw that same alligator that was friendly. You remembered it from its scar on its eyelid.
