If season 6 is Dexter's final season, then Debra probably will find out. If it isn't, however, then she probably won't find out until another season.

Yeah, I have to see how the season progresses... I think I want Debra to find out, but like nevermore said, nearer the end of the whole series.

Love Deb but she is so freaking melodramatic. I don't think I'm ready to see her burst a million blood vessels over this.

yeah i also agree wid u daenerys.

I would love to see that but i don't think it's gonna happen.. yet!

I so want to

The possibility is always there. I just hope we get a laugh out of it. I can already picture the numerous fu.ks coming out from Deb's mouth. *smirking*

But in all seriousness, I really hope the writers find a way to have the two siblings on the same team.
