I would really really love if it was Jo. Unfortunately, Sera Gamble made it pretty clear that she didn't like the character. So, I say the odds don't look good.

I dont think she said she didnt like jo... i think she said that she didnt like how she was written...not able to take care of her self and in some peoples opinon childish (i didnt think so...)
if she became a better hunter and a little more kick ass i dont think she would have minded her...
maybe they are finally going to tell us what the hell is happening with her at least! I mean come on! there is no mention of jo at all! a little weird one might think...
as always i am a dean/jo lover so i hope she is back!

Doubt it. She said "favorite guest stars." Jo is not well-loved around the majority of SPN fandom. :(

I don't think so, I'm rearlly to belive jo's come back, but I think it Seara talk about ash or misury, mabey? But I agree with someone said upstairs, jo needs a new chance!!! what's the hell happend to her after the hell gates open??????

kiss cau!

I too am very very doubtful it includes Jo, for pretty much all ther reasons listed above. (but I'm more than willing to be pleasantly surprised)

I'm pretty sure however she might be refering to Ellen at least...

I'd love for it to be Jo but what are the chances of that? I heard a rumor before the writers strike that she was supposed to guest star in a season 3 episode but they had to cut out like 6 to 8 episodes in season 3 due to the strike. I guess it's possible she was written into season 4 then.

I mean come on it's rediculous we still see Ellen but not even a mention of Jo?! That's bad writing if you ask me. You should always keep a living character in the storyline somehow.
