How do you help Kara deal with the fact that you're going to die, but she isn't going to for several centuries?
Cat doesn’t.
Frustrating is an understatement.
She tries. Letters arranged to be released for months after she’s gone, pre-emptively aiming to talk Kara through grief that she’s never felt, and loss she can only imagine. And, oh, does she have some kind of existential crisis that she refuses to let cause another wrinkle over it, hand waving over the ‘Last Letter’ thrust into Olivia’s palm like some pissy viper, cloaked in scales and snapping forward without the aim of truly striking.
Olivia will have letters, too. But those are somehow easier to write. Easier to give her. She shouldn’t have saved Kara’s for last--
Ridiculous final letter. Is saying goodbye so hard? Why wasn’t this topic covered in Fifty Ways to Leave Your Lover. What is that final letter but a second death? It’s cruel. It’s cruel. A writer’s greatest, final nail tip-tapping away on a coffin like some undead Gene Kelly tapdancing on her satin-lined grave? Cat’s final work.
It should have been my Magnum Opus--
I’m going to ignore the fact that you just called a Posthumous Letter a Magnum Opus--
What if I make Kara feel it all, again?
Olivia sighs and they both look so old.
You will.
Cat doesn’t write the last letter until her deathbed, thanks to that. Best friends are horrible at assisting with writer’s block when they’re going to be so dramatic about it.
She tries. Quips about signing Kara up for a dating site--I wouldn’t mind watching from the great beyond, Kara--
That’s not funny, Cat--
--Despite knowing that it’s futile.
Maybe it’s the most futile effort because trying keeps her from having to write that damn, last letter.
Be angry, she so wisely--so omniscient--pleas in the afterlife. Let yourself be angry. Let yourself feel. Let yourself be whoever you are with me and without me.
Cat writes and writes until her fingers bleed, and squirrels away letters like secrets even though Kara knows a month after she does.
Let yourself smile without feeling guilty--
She takes what caused it to her grave--the fact that her blood shines a tint of green that even Lena Luthor can’t fix. They don’t lie to each other, but she lies by omission about this.
Let yourself scream without remorse--
They don’t lie to each other, and maybe it’s selfish. Maybe Cat’s too selfish, so small on this too large hospital bed. She’s sounded so strong and so certain and so proud in her prose--a woman of steel in prose, who crumbles underneath a woman of steel wrapped around her. There’s a mortality that quakes the ridges of her lips when she murmurs into Kara’s shoulder--only Kara’s shoulder--
I’m scared.
And she knows, in that moment, that she’ll never help her. That she’s left a burden far too great on Kara--one she’s carried since she was a child. Watching a world wither away in her fingertips too far away to feel the heat from it fading away--too close to pretend it never happened.
She’ll leave her.
I love you--one time out of a thousands murmured against the warm skin of Kara’s shoulder, arms wrapping around her waist, nose slotting against the base of her neck when the tears have stopped between both of them. The letters won’t help. Finding someone else won’t help. Cat won’t help, she’ll only leave her.
But she’s not leaving her, yet, and perhaps the last memory Kara will recall of Cat won’t be of her dying, it will be of her fighting to stay.
It won’t help, Cat knows.
But at least Kara will know--she’ll know--
Let yourself let me go. Or don’t.
One day, far, far in the future, she’ll be able to stop fighting, too.
But no matter what, let yourself live, Kara.
She tries, but she never quite succeeds.
