I’m not able to pin down what “the edge watson” refers to from that wording alone. The most likely reading is that you mean a person named Watson and a specific “edge” or memorable moment, but the search results are too mixed to identify it confidently.

What I can tell

  • “Watson” appears in very different contexts, including sports and unrelated articles, so the phrase is ambiguous.
  • One result ties Watson to “edge” in a sports context, but it does not match your exact wording or prove the intended meaning.

Best next step

Rewrite it with one more clue, such as:

  • the full name,
  • whether it’s a football player, actor, or forum user,
  • or the exact quote/post you saw.

Right now, the safest answer is: I can’t determine why Watson “will never forget” from this phrase alone.
