They find a younger Kyle and Derek playing baseball at the park, with Derek admits his knowledge of John's relation to Kyle; John then sees his uncle as a surrogate father since. In the episode "Goodbye to All That," during one of Derek's recollections of the future war, Kyle (when he was a Corporal) and a small group of his unit attempted to save forty prisoners, including General John Connor, from Skynet's forces. However, he became trapped and one of the Resistance's senior officers, Martin Bedell, sacrifices his life to save him and free Skynet's prisoners. In the episode "The Demon Hand", it is hinted at by Sarah to Derek Reese that Kyle's ashes were scattered "in the grass"; a later episode shows that he was in fact buried in a grave marked only by the year of his death, and in the next-to-last episode of the series, Derek's own ashes are buried next to his brother, or at least in the same cemetery where his brother rests.
