especially since I read (at the back of the season 3 companion ;)) that Dean thinks he might be his too! =P ♥

I love watching those Ben&Dean moments over and over again!

I wish he was, but I don't think he is.

i wish that too!

I don't think Liz would've lied.. i mean in the end she wanted to be with Dean it was him who went away so i think if Ben was really his son Liz would of tell him! :)

I agree with Roxyn... if Ben was Deans im sure she would have told him, because she really did want to be with him at the end. Would be pretty cool if he was Deans though, it looked like Dean actually wanted Ben to be his at the end! :)

no. maybe if they would have adressed it more. but its been nearly 2 full seasons (- however many episodes). it would have have came up by now

Yeah I agree with Ana. She would of told him.
Plus even though they are a lot alike doesn't mean they are related. You don't need to be family to share the intrest. Take this spot for example:)

I don't think so but it would have been cool if he was. And Ben was so cute.

I think she lied, and while she did ask Dean to stay I still think she might have thought he wouldn't. The similarities were awesome, so no matter what I'm always going to think that Ben is Dean's.

I dont like the argument - 'Because they're similar'. There are people in the world similar to each other with similar interests but it doesnt mean they're related.

:( i broke the 50/50 tie :( but yeah i think mayybbeee...

i agree with Roxyn i think since lisa asked dean to stay that she would of told him

If Lisa knew that Ben was Dean's son and had originally lied to protect her son from being rejected, she would have told Dean the truth during the year when he lived with both of them. There's the small chance that there'd been a mistake in the DNA test so that the trucker guy was a false positive - but since Lisa and Ben were dropped years ago, it's highly unlikely that they'd return to make such a revelation.
