In my first run of the Chapter 3, the cinematic reminds me that I was fair with kenny, and that he appreciated that I helped his family and sided with him.
Then, in the Macon grocery raid, he left me under this door, staring at me like I am the next dead over there.
On another run of the Chapter 3 based on another save where I never helped him, he reminds me that I endangered his son twice. But then, he helped me to lift the door at the grocery!
So, what's wrong with Kenny? Is it a bug or intended so you change your opinion about him?
