Broken, But Burning. [SuperFlash 1]

Grief changes people. Loss rewrites them.
Six months after vanishing into the Speed Force to save his city, Barry Allen returns to a world that doesn't feel like home anymore. Iris West - his anchor, his heart - is gone. And without her, even the Flash feels painfully, humanly slow.
Across the stars, Kara Danvers knows that feeling all too well. Left behind after Mon-El's return - married, unreachable, part of a world she no longer fits in - Supergirl is tired of pretending she's fine.
When fate pulls them into each other's orbits - one hero weighed down by the past, the other haunted by the future - they don't expect connection. They don't expect understanding.
And they definitely don't expect hope.
But even in the wreckage of their worst days... broken things can still burn bright.
