There's three outcomes I can see (the second one isn't as likely).

Jordan Chase dies, Debra finds out about Dexter and Lumen's true occupation...but chooses to accept it, because of her own plotline occuring where she killed Carlos Fuentes (and didn't feel bad about it), as well as her growing appreciation for vigilante killing. As for Quinn, he may or may not end up imprisoned for the death of Stan Liddy...I don't see him dying unless Dexter REALLY wants to kill him...but from what I've seen during this most recent episode, Dexter appears to understand that Quinn was backing off and even wanted him to leave (meaning Dexter didn't want to kill Quinn, unless he absolutely had to).

Debra stumbles in on Jordan Chase rather than Dexter and Lumen, with Chase about to kill Lumen...when he goes into a monologue and tries to attack, he's shot and killed by Debra. Dexter watches as his own sister takes a criminals life...and considers telling her the truth about what he really is. In the final moments of the episode, he tells Debra the truth...and she accepts it...with Quinn also learning to accept it.

Jordan Chase somehow survives, Lumen is killed and Chase escapes with Dexter left holding the knife...Debra comes in to find her brother and arrests him...thus turning the 6th (and final, if THIS WERE the scenario) season into his life going through jury trials, prison and eventually...his execution in the final episode. Believe it or not, that would still be the side of a serial killer that is often seen in the media...the long, drawn-out trials to finally execute them. May not be as exciting as any of the other seasons though if this occurs THAT SOON.

I don't see the third one happening, I doubt Debra would arrest her brother...
