it will be Deb, i think she will somehow catch on to her brother, but i dont think Dexter will really do anything to her. he does care about her. its his sister. the only sibling he grew up with… but i do think Deb will have a very tough time adjusting to learning about Dexter and i dont think she will turn him in because he does slain the bad guys. [at least for now]

I’d also go on and guess on Deb. It’d be a cool plottwist too.

I’m gonna keep going with Deb too! I mean saying it will be Rita would be way too much, no?

I’m going to throw in Rita. She’s been close before to seeing the true Dexter. And yeah, I really want this set, too. But no one better discuss the season premier episode. The way the show is structured, the first episode is kind of the biggest!

I’m gonna go with Lt. Maria, though I strongly feel I could use a recap of season 2 to help me remember some of the events.

I’ll throw Masuka into the mix, just for fun.

Isn’t Jimmy Smits coming into Dexter’s neighborhood this year? New characters tend to get the axe (pun intended).

I’m pulling for you Jimmy!

Laguerta would be my guess

Batista!!!

Miguel Prado, hes an interesting new character this season, i bet he gets the chop, literally

It would be so interesting if it were Deb, but I’m just excited for a new season!!! I’ll say Laguerta.

I hope no one but I think LaGuerta cause she’s going to be suspicious of him after Doakes

I’m thinking Laguerta too.

I agree. I think it will be Jimmy Smits.

Whoever gets close to finding out will go next - either Rita or LaGuerta.

I’m going to go with Deb too! ~ Thanks!

I think it will be Rita. This can free up Dex to found a new love .

Deb. I just know it…..

I honestly think its Deb.

i could see her finding out about her brother, but she wont turn him in because its her only family and she will realize he is actually killing murderers & criminals, but it will take some time for her to get used the idea considering she’s an officer of the law and all.

dexter will also have the issue of someone close to him finding out, but i dont think he would ever hurt deb

LaGuerta seems the most likely considering the books.

Oh my! Now I am hooked on watching Dexter! My husband was the one who loves watching it and I really had no idea how great the drama was untill I watch it myself. Now I am looking foward to get my hands on season three. Just started watching season two though’…. No idea what happen in season one… Would be nice if I get to watch it!
