Revisionist History - Sandrine Shaw - The Flash (TV 2014) [Archive of Our Own]
When an evil meta messes with the timeline, Barry is forced to go back in time and restore things to how they used to be. It doesn't quite work out the way he thought... But on the scale from a megalomaniac meta enslaving humanity to accidentally killing your friend's brother, dating your recently deceased sometimes-nemesis-sometimes-ally barely seems like a blip on the radar.
The front door has barely fallen shut behind Barry when the all-too-familiar voice calls out to him.
“So, how was your day, dear?”
Sarcasm curls around the words, turning the term of endearment into something sharp and mocking. Barry’s glad that some things never seem to change, even if everything else does. As he steps further into the apartment, he finds Leonard Snart sitting on his couch, arms spread across the backrest and a glass of red wine in front of him, a picture of domesticity.
There’s no good way for Barry to answer the question. How do you say, A meta changed the timeline into some awful kind of dystopia, and then I went back in time to fix things, which worked out reasonably well because everyone is alive and more or less happy and it’s almost like it was before the whole mess started, except now we’re apparently in a relationship, sorry about that?
He rubs the back of his neck and looks away, unable to bring himself to meet Snart’s piercing stare. His gaze falls on the picture frames on the book shelf – a smiley snapshot of him with Iris and Joe, a younger Lisa blowing a flirty kiss towards the camera, and right there in the middle, a photo of him and Snart together, the old smirk on Snart’s face but an unfamiliar softness in his eyes, and the Barry on the picture is looking at him the way he knows he used to look at Iris.
The photo hammers home that this is real, that it’s not some kind of practical joke, that this is his life now, and he remembers Jay’s lesson about trying to fix the past. How you can never quite go back to the way things used to be, never glue the broken cup together without the cracks showing.
