OMG I KNOW!!!!!! WHAT!?!?!?! I literally screamed "No!!!!!" at my tv at the end. I'm so sad...I loved Nate. Hopefully he'll appear as a ghost like everyone on the show does.
I guess they had to do something dramatic since it's the last season.

On one hand I'm sad because Nate's gone. On the other hand I'm pissed at him for how he acted toward Brenda. What a selfish bastard!

I was kind of hoping that he'd come back to life, the way he did a couple of years ago. But the Scenes From Next Week show that he's definitely dead. :(
