So I didn't see the walker bite Lee, and the wound honestly looks more of a scratch to me. I know this is like the "Oh the shot didn't kill Carley" thread.
After looking at his wrist it looks like a scratch maybe? Or hell maybe it is a bite.
Also if any mods see this please change title to "Bite or Scratch" I keep looking at my typo and its bugging the hell out of me.
