All I can say about last week's episode regarding Jack and Syd is....
HA! I KNEW IT!!!!
I've been saying since what seems like season 1 that if Jack had any doubts about Syd's parentage, he'd have her DNA tested and that he truly is her biological father.
As for tonight's episode....
AAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHH
My mom and I both screamed when Jack jumped Katya at the end. HOO I so didn't see that one coming and neither did my mom.
Vaughn's an idiot who really needed to be slapped tonight. And no, I'm not a syd/Vaughn or Syd/Sark shipper. I personally think the best person she could be with is Will. But that's just me and I'm in the minority on that one.
