there is no way Jack is gonna be evil. JJ always did that and made sum1 out to be the bad guy like in Season 1 with Kausinau as the man and it turned out to be Syd's mom, he always changes characters between it and i doubt even with the new directors that that will change. i do believe that he is hiding something from Syd and that he betrayed her trust, but i dont think that he is evil. i dont even think that the guy there was Jack due to the whole mask thing. ya, no one can impersonate his voice but Syd did it perfectly with Laurens voice. plus, jack came there minutes afterwards so who nos if it was a set-up or not. i think that he may have connections with the covenant b/c if they can get lena back, she mayb the HOC, so Jack let Syd be b/c those papers had to do with Sydney when she was missing and Jack had a project to find her and he found out she was active but he did not pull her out and quit the search. but there is probably a real reason. J/S relationship isnt jus gonna get ruined like that, but the whole weapons thing could jus be some other skeleton in his closet.
