hmmm, i'll choose jack since edgar stiles isn't one of the options.

its Philip...why else is he so obsessed with the kid?

Josh is like the male version of Kim - blonde, short, whinny as hell and way to prone to being kidnapped!!!! If it were me Id order paternity test to sor this whole thing out, but my votes for Jack to be Daddy dearest!

OMG, he is so Jacks son! But that will be another story line in the future I bet.

thank fuck sumone else picked up on this! i had been thinkin this since the 'character' of josh had been introduced. i say 'character' coz he aint much of one really! but serially! if u look at them, josh has the pure aryan features that hitler but be proud of as does kiefer! ah duh! u big mong! of course the boy is jacks! altho that means that jack slept with 'Wheels' ...oh wait, mayb its in heroes that she has wheels!!...

I think Graem is his dad... I don't know why.. gut feeling.

I believe it's Jack. Actually, I'm surprised they didn't go into that storyline more last season (Day 6). Hopefully, they explore more in the future...maybe in the movie.

I think Gream is his dad. Although Jack and Terri had some difficulties I don't think Jack would've cheated on her during the marriage. Not with Kim being a small girl(take Kim's age of 25-ish minus 16 years equals 9-ish). Nah, I don't think Jack is Josh's dad.

duh!

No. I don't think he's Jack's kid.

It seems a bit cliche, but I still pick Jack.

Graem is ugly, but Jack didn't cheat on Teri as well!
