(posting this now but planning on adding more as I think of it)
  1. Erin's reunion with her family
  2. Kelly finding out she was actually going to Miami University in Ohio not University of Miami
  3. Erin real name being Kelly
    They only mention this in one episode and I think it could have been a really good running joke
  4. Michael and Holly having kids
  5. Date Mike (Michael struggling with dating)
  6. Dwight and Angela's life with Phillip
  7. How the senator dealt with finding out Phillip was not his child
