In the first episode of season 2, when clem meets Sarah, her definition of "something horrible" is her father saying he is dissapointed in her, and is only looking out for her and that he loves her.
This is bad.
Sarah has no grasp of just how bad the world is, not even an idea, she is practicly a ticking time bomb waiting to explode. The question is, what's gonna happen when she realises what the world really is? and whats left?
What do you think? will she "cease to function" as carlos said? will we be the ones to break it to her? how do you think it will play out? and how do you want it to play out?
Honestly i think it would be interesting if who makes her realise the truth about the world depends on the players choices and its impact story-wise is different depending on who ends up doing it "the two people being Clementine and Carlos"
