Could the dragon tat be a reference to the band Kraken? Kraken was another word for sea monster. Another thing I noticed, looking at the tat, there is definitely what looks like a rope noose in the middle of the dragon. Right beside the noose and following the same loop, is what appears to be a leopard-print spotted snake, almost like the dragon overlays the snake and noose.
