Yes, it's true, the man who left me my time traveling watch was my dad [DUN DUN DUNNNN].  Now for those of you who aren't listening week to week and accidentally saw this synopsis before you watched the previous episode, I bet you're feeling pretty foolish right now for getting such a great mystery spoiled.  Let this be a lesson for you that I am most definitely going to spoil previous episodes in my synopses, and why are you even reading the synopsis of a future episode?  That's really weird.  Anyway, the guy claims to be my dad but I need proof before I call him daddy, so he shows me proof by taking us back to when he met my mother.
