I posted this already in a thread about 47.1, but it's a past episode and everyone moved on (which makes me think about the finale: the community will be fractioned right at the most important moment in the series, but anyway)
So, Ink tattoes himself before the outbreak; after the outbreak he tries to find out which symbol protected him by experimenting at the jail. Except he is a zombie, i.e. he turned, i.e. by definition he was *not* protected. He has no reason to think any of the symbols protected him from being attacked and turned, because he was attacked and turned. I am stuck here.
