Blue Sky (fanfic)/YMMV

• Alternate Character Interpretation: This is not the fanfic for an interpretation of GLaDOS as in any way well-meaning or kindly disposed towards Chell. This GLaDOS is a pitiless monster, and the story makes clear that the redeeming qualities she showed in Portal 2 were entirely thanks to Caroline, now deleted. Wheatley is shown in a sympathetic light, but with his many flaws thrown into stark relief.
• Earn Your Happy Ending: And how! Wheatley's redemption comes at a hefty cost, but his courage to face death and separation from Chell wins the safety of Eaden. And thanks to Caroline, Wheatley is granted a human body and a life with Chell, while GLaDOS gets to go on testing, far, far away from them.
• Nightmare Fuel: Take all the Nightmare Fuel of the previous Portal games and let it simmer gently in memory. Chell is in many ways a Shell-Shocked Veteran of the Testing Facility, still suffering severe PTSD.
• The Woobie: Wheatley, oh heavens Wheatley. Fresh from 300 years of entropy in Aperture Labs and four years in cripplingly boring orbit, he arrives in Eaden, set to fail at everything he sets his hand to, from making bread to just being a decent person. He's crippled with constant self-doubt and self-loathing, feels terribly out of place among humans, and his backstory reveals that he was just an ordinary, perfectly innocent Aperture Science employee who was abducted, tortured, and then rendered immortal so the scientists could try and save their own skins -- and he was programmed to have terrible ideas and never recognize them as such. Profound Woobiedom.
