Davy fell in love with a woman who wasn't right for him..she was actually the sea goddess calypso and Davy just couldn't live up to what she wanted in life, she was too untamable for him... so she left him at the alter. Davy became so heartbroken that he cut his heart out...It's exactly what is happening with Will and Liz so far in the story...
nah he wont...If he does I'm sure is dad would stop him..Bill saves Will 3 times in movie 2 from a worse fate..those scenes seem pretty pointless in movie 2 but if the same kind of interaction is repeated in moviie 3 where Will's dad saves wWill from a horrible future... then those scenes make perfect sense to be in movie 2
