Dr. Stoner bringing out the other Cobra - what if?
After Dr. Stoner successfully changes David into a Cobra, he suddenly decides to bring out his other Cobra out to the yard. But unlike earlier in the movie when he was giving a show, Dr. Stoner is cannot charm the Cobra as it kills him with two bites.
1. Why did Dr. Stoner suddenly decide to bring out his other Cobra?
2. Why wasn't Dr. Stoner successfully charm the Cobra like he did earlier?
3. Suppose Dr. Stoner didn't bring out his other snake and he was not killed. What would have happened to him? The police were on their way. I suppose he would be arrested and charged for sure - what for what? Any evidence David is now a Cobra?
