CONTEXT: Agent K (Tommy Lee Jones) witnessed the death of Agent J's (Will Smith) father, who was killed by an alien in an act that could have been prevented by Agent K. Considering the time travel elements of the third movie, and the fact that Agent K from the past was aware of his future after Agent J told him, he has essentially lived with the fact that the father of one of his only friends in the universe died because of his own failures. Since the "past" elements of the movie took place in 1969, this means he's lived with this memory for some 40 years.  <sep>  Q: What happened to Agent K to make him so grumpy and emotionless? A: Agent K (Tommy Lee Jones) witnessed the death of Agent J's (Will Smith) father  Q: So how did Agent J's father die? A: was killed by an alien in an act that could have been prevented by Agent K  Q: Oh, so do you think that he was stoical and cranky because he felt guilty about that? A: he has essentially lived with the fact that the father of one of his only friends in the universe died because of his own failures  <sep> FOLLOWUP_Q: Wow, so does Agent J know this is how his father dies?
