Oh, dude. Totally. Because if he's creeped out by rats, it makes perfect sense that snakes will give him heebie-jeebies.

But even more importantly? It's on an AIRPLANE. That's a brilliant connection you made. Only his adoration for Sam Jackson (and affection for Sam Winchester *g*) could outstrip his fear of flying. I mean, an action/horror movie set on a plane? That's gotta creep him out to no end. Heee! And Sam would totally know this. That butt.

Well-played, my dear. Very well-played, indeed. :D
