Dungeons & Dragons

Plot:

With Derek Reese severely injured, John calls on Sarah's former fiancé Charlie Dixon, an EMT, to provide medical assistance. Sarah finds herself having to explain where she has been for the last 8 years and just who Derek is and where he is from. In flashbacks (of a sort) we learn of Derek's life in the future as a resistance fighter, his relationship with John Connor, and of his travel back in time with a team sent to help Sarah and John. Derek doesn't know that his brother Kyle is John's father.
