* Trev will begin his speech only after you enter the room, but will change the music when he sees you. Shooting at them, leaving through the door, or being within 25 units of a spot near them will start the countdown. <ref name="function explorer misc facts">{{cite web | url=https://forums.the-elite.net/index.php?topic=18518.msg455830#msg455830|title=the-elite Goldeneye facts topic post on miscellaneous function explorer facts|author=Icy|access-date=July 16, 2021}}</ref>

* Natalya will be shot by Ouromov 30s after Trev says "That's close enough!".
+
* After 20s from when Ouromov was killed, Natalya will run towards you whenever you're near the train exit.
+
* After 50s from when Ouromov was killed, Natalya will say "He's in Cuba!" and complete the objective.
+
* After 75s from when Ouromov was killed, Natalya will say "Got it! You're a slug-head, Boris!" and complete the objective.
+
* After 15s from when anyone was attacking, Trev will say "Good luck with the floor, James!". If Xenia is dead and faded out, this takes 30s instead. 5s after the message, the countdown starts.

Despite Nat becoming active after 20s and the countdown starting at 20s, the two slightly different triggers, as well as lag, may be why the objectives appear to complete with a few frames of leeway when using the countdown timer as a measure.
