The wife and I were talking about that, just like everyone else apparently.

A couple of thoughts I have, one I really hope isn't true.
First, I expected Derek to die. Seems he's been a bit weary of his "mission", so they could only play him being useful for so long.
I think they knew everybody expected a huge out for him. In a way, I'm almost happy to see something unexpected. Just hated to see him go.
Second, I know the series has been on a rollercoaster of possibly getting renewed, canceled, ended, etc. I just really hope they do not start a trend of killing off main characters just to hurry up and finish. The series obviously can't go on forever, there is only so much timeline. Just do the ending right.
Now what would really be cool in a cheeseball sort of way....
Since they kept mentioning characters having different timelines, what if future John now knows what happens to Derek and there is now a more prepared Derek sent back. =P
Won't happen, I just hope for atleast one more season.
[quote name='captainfrizo']I was shocked to see Derek get killed the way he did. I would have thought he'd go out sacrificing himself to save John as he repeated many times people will die for him or taking the other terminator out with him. To have him walk into a room and get killed immediately without a fight or anything does the character a huge injustice.
Sure, they achieved the shock value, but for a major character with connections to the Conners as he did (being John's uncle and all) I think a bigger and more dramatic death scene would have been more appropriate.[/QUOTE]
