Uh... WTF?

"Driving in Santa Barbara, Syd suggests to Vaughn that they blow off the big wedding and elope. After professing their love, Vaughn reveals that that he was a bad guy before they met. He continues to say that to begin with, his name is not Michael Vaughn. Before Sydney can react, a car collides with theirs."
-from the abc.com summary of "Before The Flood"

I was reading ABC's (rather craptastic) summary for the finale, looking for something else, and I came across the bolded sentance up there. Now, admittedly, I wasn't paying that much attention to the Syd/Vaughn stuff when I watched my tape of this episode yesterday, but I'm pretty sure I did not hear "Syd, I'm evil" or anything like that.

So... Is Vaughn evil? Did they slip up and tell us something they didn't mean to, there?

Thoughts? Opinions? Anyone?
