It's the moment we've been waiting 6 years to see -- what happens when Deb (Jennifer Carpenter) catches Dexter (Michael C. Hall) in the act? Well, "Dexter" fans, here is your answer!

Showtime just released the first two minutes of the Season 7 premiere episode of the hit serial killer show, after previewing it for fans at Comic-Con on Thursday.

As you recall, Season 6 ended with new Lieutenant Deb walking in on her step-brother as he murdered super-psychotic killer Travis Marshall (Colin Hanks). Dex looked over to see her horrified face and muttered the words, "Oh God" ... then the credits rolled.

Now, watch below see the long-awaited confrontation between the siblings! And just to say it, *SPOILER ALERT!*

So what's next? Does Dex attack his sis? Does she cover up for him? We need to know!

The full Season 7 premiere of "Dexter" airs Sunday, September 30 on Showtime. Will you be tuning in? We sure will!
