Other mistake: Irv and Blaire's death scene doesn't make sense. When Irv poured butter on the popcorn, he should've noticed the spider in the bowl. Also, when Blaire picked the spider up, she should've felt it. Both of them still appeared to be watching the TV after being bitten, which also didn't make sense. Why didn't they have seizures like the other victims?
Doctor James Atherton: In this first generation, the original male also produced a queen, and together they will construct a primary nest which the queen will guard. But eventually, she will create reproductive offspring of her own. And when that happens, this town is dead... and the next town... and the next town... and the next one, and so on.
