Laurie Strode’s son was John Tate in Halloween H20: 20 Years Later. In that timeline, he survives the events of the film, but he is not part of the later rebooted continuity , which is why he seems to disappear from newer Halloween movies.

What happened

  • In H20 , Laurie is living under a new identity and trying to protect John from Michael Myers.
  • In Halloween: Resurrection , the story shifts again and John is not included , which makes it look like the character was dropped rather than given a clear on-screen fate.
  • Later films, especially the 2018 Halloween continuity, ignore the earlier son storyline and instead give Laurie a daughter, Karen.

Quick takeaway

If you mean the Laurie Strode son from H20 , the simplest answer is: he was written out when the franchise rebooted its timeline, not killed on-screen in the main continuity.
