The nurses have a running bet going about who the visitor is. He's not the old woman's grandson; in fact he doesn't seem to be a family member at all. Her records show that her children are dead and they didn't have any children of their own. Paula thinks maybe he's her lawyer, but the others laugh at her, noting the way he gently brushes the hair out of her face and holds her frail hand, not to mention the fact that he's there every day, without fail, has been since three days after the woman fell into her coma, and that was two months ago. Some days he'll read to her, and they've already gotten through Tess of the D'Urbervilles and House of Mirth. Other days he'll talk to her, always softly enough that none of them can overhear. Gillian and Rahoul both think he's some torrid love affair from her past, noting how he'll only ever describe himself as "an old friend," but the others don't buy that either, seeing as there's no way he's a day over thirty. And she, well she hasn't seen her thirties for a good sixty years. Milla, always the creative one, thinks she was a teacher of some kind to him, maybe piano or art.
It's been a month and a half since he first started coming, when she gets her second visitor. He's dressed similarly, all black, with a black leather coat, but he's smaller and has curly, sandy-colored hair. Just as gorgeous, if not more. The nurses bore of bets over the first one's identity and start taking a poll about which one's more fuck-able. It's a close race, but a hint of an English accent is putting the smaller one slightly ahead.
The first time the English one comes, they're sure it'll be his last. He storms into the room and starts yelling about not being informed, but they can't hear much more because he notices them staring and lowers his voice. Barely two minutes later, he bursts out of the room, almost knocking over the orderly who's preparing to go in and intervene. They don't see him again until the last time, but Paula, whose shift starts at four am, keeps complaining that someone is leaving the window open.
It's three weeks later when her condition worsens. The doctors explain to the first one, who they've now dubbed "The Mystery Visitor" that she doesn't have much longer, and asks if there's anyone he'd like to call. He doesn't respond for almost a minute, before saying there's no one and he'll just stay by himself. Ten minutes later though, he makes a call and it's not long before the other one appears, seemingly out of nowhere.
When Gillian goes in to check on her, she finds the two of them sitting wordlessly, side by side. They sit like that until she dies, six hours later.
They leave together, the mystery visitors of one Buffy Anne Summers, aged ninety-eight.
