I wonder if they infect others with thier teeth. Tanya said it came out much easier than expected.

Remember I had that theory about Zombie Venom; way back when they were reviewing the video tape of that one biter who was salivating? I proposed that maybe the biters had the ability to "choose" who they infected. Like if they salivated enough in your wounds it was more likely to infect you, whereas if they didn't you possibly could survive a bite or scratch. Though I don't know what purpose not infecting a victim would serve. I just figured maybe that's how Datu and other playthings of Pinstripes managed to not get infected during capture.

Anywho, another reason, a more likely reason that the Inklings teeth fall off is to that they remain deadly sharp, just like a shark's teeth. Though I didn't hear Tanya comment on the sharpness of #2's teeth, just that she only had about 8 of them in the front.
