The player can no longer play as Tr

The player can no longer play as Trevor after the completion of this mission and any Trevor-specific activities are no longer available including property management. The Vanilla Unicorn remains available as a strip club, but it is no longer usable as a safehouse. Trevor's Bodhi will be permanently destroyed, unless the player has stored it after stealing it from Trevor.
Michael and Franklin will no longer hang out with each other because Michael is upset by Trevor's death.
Should the two pass in the street, they will have a short conversation, with Michael admitting that he is affected and blames Franklin for it, to which Franklin replies by saying he helped him, though Michael concludes that it was Franklin's idea. Finally, Michael claims that he "needs some time".
Jimmy will no longer hang out with Michael due to being upset that Trevor is dead but can still hang out with Franklin regardless who killed him.
Franklin also can hang out with Lamar but only at night due to laying low from Stretch.
Michael and Franklin will receive their shares from the Union Depository heist along with half of Trevor's share.

Jimmy De Santa - Jimmy also calls Michael asking about Trevor's death, Michael says that Trevor was dangerous and wanted to kill all of them, and that now he is not going to bother them anymore. Jimmy then ends up deducing that his father had something to do with it.

Trivia
The mission name is a reference to Steve Haines' quote from "Lamar Down" where he says that Franklin has to do "something more sensible".
Even if the player shoots Trevor in the head while covered in gasoline, he still screams while on fire, due to the script of the mission.
If Franklin doesn't shoot Trevor, Michael will.
In the PS4/Xbox One version, there's a glitch where if you let Michael shoot Trevor, after the tanker blows up, a few seconds later, Michael is killed in an offscreen explosion, therefore failing the mission. The glitch can be seen here.
The gold medal objective is still achieved regardless if Franklin or Michael shoots Trevor.
"Don't Come Close" by Yeasayer plays at the end of this mission, in the beginning of the ending credits. It is featured on Radio Mirror Park.
It most likely was chosen because it easily represents Trevor's feelings against Michael; for betraying him yet again, in order to get himself and others out of a bad situation.
Both Trevor and his truck cannot be damaged during the car chase. However, shooting Trevor will cause visible bullet holes on his torso and arms. They will stay on his body until he is killed.
In Fresh Meat, Franklin tells Michael that he "burned every motherfucker [he] has ever known", and in this ending, Trevor burned to death.
If the player skips the cutscene when Trevor is burning, Franklin will change outfits to a white tank top and brown or green shorts.
Trevor will always wear a white t-shirt and blue jeans, even if you switched his clothes before this mission.
Michael will always wear a gray suit during this mission, making this is the only ending where he does not wear a leather jacket and jeans.
The suit is similar to the one he had when hiding out of Los Santos in Trevor's Trailer.
Trevor sometimes says, "Why hasn't someone sensible shot you yet?" when insulting pedestrians, foreshadowing his possible death and referencing the name of this mission.
After this mission is completed, some Bleeter posts will mention Steve Haines's death and Merryweather closing their operations in the USA. Both of these events refer to The Third Way ending. This is probably just an oversight by Rockstar, though. Although Haines does mention Merryweather closing their operations in his post-mission phone-call.
When the credits start rolling, just before the screen fades to black, the player can control Franklin for a few seconds, which may cause a humorous result, such as jumping off the cliff.
