he dies at 24??

Yes

aw rats

Basically

2nd game, Five gets turned into The Apex by a bunch of ex-Nexcon scientists, her last words to Clarke are to ask to take care of her 5 year old sister you meet earlier in the game

And in the 3rd game you have to settle scores with antagonists from the 1st game, all while teaching Five's sister (who is now 13 at the time of the game) how to survive

FIVE NOOOOOOO

Yes

The final 'boss' of the game is a full-on horror segment where you have to escape this Nexcon facility while Five is hunting you as The Apex

NOOOOOOOOOOOOOOO

And she is too tough or quick

So you can't even kill her, you can only leave her to her fate as she escapes the facility as well and goes into the wilderness
