TWOK:
1. When the Reliant enters the Ceti Alpha system on its search for a planet for the Genesis experiment, have them recognize Ceti Alpha V and the disaster that has befallen the system. Have Terrell and Chekov attempt to render humanitarian assistance to Khan's penal colony, but they get outsmarted and captured by Khan. Things proceed as in the film from there.
2. Instead of taking Preston to the bridge before taking him to sickbay, at that moment have Scotty appear on the viewscreen from sickbay with the same look of anguish that he has in the film, as McCoy attempts to treat Peter in the background.
3. Have Carol hold back a password that's needed to fire the Genesis Torpedo. Carol tells Kirk that Khan wouldn't even know a password was needed until actually trying to detonate the device. Kirk then baits Khan into the fight in the nebula by revealing to him over radio that he cannot fire the torpedo without the password and he lacks enough technical information to safely fix the device so it will work without it. Khan's concern is therefore boarding the Enterprise and capturing Carol. But Kirk doesn't invite Khan for a rematch in the nebula. Instead he acts like the Enterprise is fleeing into the nebula, with the deception as to how repaired the Enterprise is still in effect. Khan thinks that Kirk is only trying to delay him until help arrives, so he figures that he must act quickly and decisively, so he pursues Kirk into the nebula. Kirk then surprises Khan with weaponry that is more operational than Khan was led to believe, which wins the battle without the two-dimensional thinking/zee minus ten thousand meters schlock. But David says that when Reliant explodes it could set off a chain reaction in the Genesis matter that will destroy the Enterprise unless she can warp away. The creation of the Genesis Planet occurs because protomatter was used, which is part of the reveal concerning this in the next film (that's one change for STIII).
