Are the headcrabs on the zombie's back jealous that they don't have a head to suckle on? Is that why they climb all over his back? And why he has to throw them at you himself and they don't just run like every other headcrab?

And why can zombines run but normal headcrab zombies can't? They appear to be wearing normal headcrabs...
And why aren't there fast headcrab zombines? And poison headcrab zombines?

If every headcrab zombie looks the same because of the civilian dress code, why do the civilians wear blue jackets but the zombies wear white shirts? Are they the undershirts? If so, why didn't a single one manage to keep it's blue jacket on?
Also, where are the resistance member zombies? They seem to wear different clothes, and surely some have fallen prey to headcrabs...
