I do not think she lied about coming to the island by accident. But maybe we will see.

I'm with you on the Black Smoke having the 'mind' of MiB. He was in some way transformed.

I wasn't sure the kid was young Jacob. I was going to go back and look but I have not done it yet. But not only the MiB sees young Jacob... everyone else sees him too!! Could young Jacob be a second Black Smoke??
