Before Artemis, before Zatanna and Raquel and Bette and Barbara, Valentine's Day had been reserved for just the two of them.
They would spend the day playing at an arcade or riding down the slopes of a rollercoaster at an amusement park or stuffing their faces at an all-you-can-eat buffet. And during the night? They'd patrol either one of their cities, easily disposing of any kind of crooks that came across their paths.
Valentine's Day was meant to spend with the ones you love, right? And they couldn't think of a better way than to spend it with each other, their very best friend right by their side in the twilight of amour.
However, once Wally found Artemis and once Dick found Zatanna then Raquel then Bette and finally Barbara, Valentine's Day fell away from them, slipping through the cracks of their childhood memories and halcyon days.
And so, the night Wally returned to Artemis and Dick returned to his apartment in-between the relationships with Bette and Barbara, he had one resounding moment of clarity before it vanished, swept up in the tide of red hair and blue eyes that came the next day.
Perhaps it had never been about friendship.
Perhaps it had always been about love.
