You can be indifferent to decisions or say Kenny or Lily is the leader. But he does kind of step it up regardless xD
We were working on three files. Mine, my husbands and one I randomly decided to to.
He sided with Kenny, I sided with Lily, and in the third I was basically the asshole (didn't care, instigated fights, made bad decisions, etc). I based most of my decisions around Clementine (for example, not killing the brothers).
