Quoted from rai:

Agreed it's almost as if Borg has never watched the films and just said there are 10 characters in the film let's pick one and make that the focus. I have not played the pin obviously, I'm just looking at it. It's like if they made a Star Wars pin and build it around the Ewok TV show (for example) yes Ewoks are a part of the SW universe but they're not the main focus.
I will say, the same thing with TWD, just like Borg said 'let's see there was a well walker and a bicycle girl in a few scenes so let us make that two main shots'. Was there an arena (yes there was a scene in the show like 10 minutes) so they let's make that a mode, let's make Barn a mode (etc..)
Basically everything in TWD technically was part of the TV show but most likley just a 10 minute or half an episode and the head in the prison makes no sense at all. But at the end of the day TWD is a fantastic pinball machine.
