Chapter 47-1 The Lion's Den

[clem131]

Ok, I know I am now SUPERLATE, but as I mentioned I wasn't here, then listened to the episode on the plane back from vacation, blablabla, anyway:
I am stuck on part of Tanya's reconstruction of past events. Briefly: Ink is not turned, then he gets attacked. The biters grab his arm through the window of the police truck he was in, and don't see the protection symbol he has on his face because the windows are probably very small or narrow. He is bitten and he turns.
So, from now on, when he leaves the truck, there's no surprise the biters don't attack him. He's one of them.
At this stage there is still plenty of humans around, they are certainly not starving and not eating each other, this is the initial bloody phase where most of the human population is wiped out.
So I don't get this passage: why does he embark on a project to find out which symbol did protect him when in fact he wasn't protected at all?

There's the possibility that Tanya got it wrong, that he did not turn (after all we only have low quality security footage to assess that) and he in fact improved himself using the same substances he used on zombies. I don't buy it, though: we have so many clues that he is a zombie as well, and Tanya's sequence this episode was clearly meant to be "Tanya's fun explanation hour". It would be a cheap and bland use of the unreliable narrator. So I believe he was turned, which means for all he knows the protection symbols didn't work.
