I knew Glen was a goner, as soon as they did the ultrasound.Comics aside...he should have died a long time ago honestly. While I appreciate the arc they did with him, he's been on the bottom end of it as far as staying alive to long.
But it's an economic decision. They kept Glenn on, because he was cheap. Furthermore, they needed the token Asian to snare my market (as our representative) until we all got hooked and so invested that we couldn't leave the series, even if they offed the poor pizza delivery Korean guy.
Heck, you should be THANKFUL they kept him on. After all, there's over 2 billion of us and the fact that a lot of us watched it, probably paid for seasons 5,6, 7 as well as #8!!!
