Jeremy Aster

Story: The Bonding
Written By: Ronald D. Moore
Series: Star Trek: The Next Generation
Year: 1989

Terrific episode. A kid on the Enterprise is put through the traumatic experience of losing a parent when his mother dies on an away mission. He is orphaned, but he is having trouble accepting her death. This is further complicated by an entity of some kind mimicking his mother and appearing only to him. But the episode is about the death of a parent. So Worf, who led the way mission feels rather responsible. He ends up performing a Klingon ritual, which makes Jeremy his brother.
Of note about this episode, it was originally submitted by a fan, and thrown into a reject pile during the tumultuous behind the scenes problems of Season 1 & 2.  When Michael Piller came in and began to shape up the production a bit, he went through the reject pile, found this script and hired the young fan, Ronald D. Moore...who went on to become one of the biggest contributors to the Klingon Mythology as we know it, and would play a major part in the writing staff of TNG up until it's end (and first two films), as well as much of DS9.  If you'd like to see his start, it is right here.
