In the last couple of minutes we see Kyle with one of the promicin shots. I wonder if they're trying to write him off for good. With this promicin shot being 50/50 and all, the writers could just say, "his body rejected the promicin", add in a few touching words, and no more Kyle.
I hope this doesn't happen. I personally like Kyle as a character, and it would be such a shame to waste such a potentially rich character because of contract issues.
