I FOUND who the THREAT for Claire's BABY is!!

Everybody's BEEN wondering sick WHAT the danger WAS for baby Aaren, AND I have FOUND what THE threat is!! In the beginning OF Fire + Water we SAW the father of Charles and Li-am, and for a SPLIT second, we see him CHOPPING a baby doll's HEAD of!! THIS can only mean one THING!! Aaren is going to HAVE his head cutt of by Charles' DAD if Claire doesn't watch OUT!! This WILL mean that Charles' DAD is on the ISLAND!! Maybe he's THE one WHO bought Charles' piano!!
