Now we all know that Richtofen is in his head giving him instructions on how to complete the tower of babble but what if in the dlc he here's different voices. Maybe he can here the original characters like takeo or Dempsey or even Nikolai giving Samuel instructions on how to send them back to earth. Possibly maybe he could even hear Samantha. Who knows? What do you guys think? Also in the future maybe the 4 original characters and the new current characters meet up and join forces to take on the incoming zombie apocalypse.
