Luke could have made it into season 3
So i was thinking about this and realized that TellTale easily could have written Luke into season 3. Here's How I would propose doing so:
Luke falls through the ice, bonnie drowns trying to save him but Luke survives. Luke would be incapacitated for the night whilst recovering, then all the shit breaks loose, by the time Luke stirs awake, Mike and Arvo have ran and Kenny is telling Luke they need to leave. NOW. Luke and kenny later get out the car together to look for diesel, end up at the rest stop, Luke is resting with his back to the wall, (hes very weak) with his leg outstretched to take pressure off the wound. W hen the fight breaks loose, Jane and Kenny cause a shelf to be knocked out of place, falling and knocking luke unconscious, the fight then takes place with Clementines choice being made, just as Kenny stabs jane or Clem kills Kenny Luke staggers out of the door exclaiming "wait...stop....." then our choice takes place..
Would have been perfect to have 1 non-determinant character follow with clementine into season 3.
