"So he took you onto his ship and ended up teaching you how to sail it?"

There's a trace of disbelief perhaps in the latter statement. Not over the truth of it, that was proven some time back, but rather the fact of Hook doing it for no reason but to be friendly. He had to wonder just what the story was between the rescue from the water and the teaching and when and how his son parted ways from the pirate to live on the island. He wondered how soon Hook realized just who he'd rescued and if the pirate had intended to use his son against him in a similar manner that his attack on Belle had been actually directed towards him.
