It's funny how a single moment in your life, can change everything. One decision, or lapse of judgment can drastically alter the course of your life. It only takes a split second, for all of your plans to change.

She knocks on a familiar door. Her hair is pulled back into a ponytail, she's not wearing any make up, and instead of a dress, she has on a pair of yoga pants, and a t-shirt. She waits a few seconds, but doesn't hear footsteps. She raises her fist, and knocks on the door again.

"I'm coming," the voice on the other side tells her.

Jane pulls the t-shirt on, over her head. She stops, and looks through the peephole. She finds a familiar face standing on the other side. She briefly checks the time on her phone. She silently curses herself, and unlatches the door. She pulls it open.

"Maura, I'm so sorry, I overslept."

Maura says nothing, she just enters the apartment. Jane closes the door behind her. She looks at her watch. Maura walks past her, not making eye contact. She takes a seat on the couch. Jane furrows her brow, in confusion. She walks across the room, and takes a seat on the coffee table. She looks at Maura, trying to gauge her expression. She taps her on the knee, as Maura stares off into space.

"Maura what are you doing here?"

Maura doesn't answer, she doesn't even make eye contact.

"Maura? What's going on? You were supposed to be in surgery right now."

"You didn't come to pick me up."

"I'm sorry. I didn't mean to make you miss your appointment."

"I went, without you."

"You couldn't go through with it?"

Maura looks up. She finally makes eye contact, but her facial expression doesn't change.

"That wasn't it," she answers.

Jane notices that Maura is still wearing an ID band. There is a band over her left antecubital.

"But you went. Do you want me to cut that band off? I have a pair of scissors."

Maura looks down. She stares at the band, "I didn't even realize it was still on there," she admits.

"Maura are you ok?"

Maura shrugs, "Why wouldn't I be?"

"You're supposed to be in surgery. You were going to donate a kidney today. Instead, you're here, in my living room, with this blank expression on your face."

"I don't know what to say."

"Tell me what's going on," Jane insists.

"I wouldn't know where to start."

"You went to the hospital?"

"Yes," Maura nods, in confirmation, still fixated on her ID band.

"And then?"

"I came here," Maura replies.

"I know that. What about in between the time you got to the hospital, and the time you got here."

Maura shrugs, "I don't know it was all a blur."

"Maura, what is wrong with you?"

"Nothing," she lies.

"Clearly there is something wrong with you. You look as if someone ran over your dog, or something."

"I don't have a dog," Maura responds, emotionlessly.

"Maura what happened? Did you change your mind?"

"No," she shakes her head.

"You're pretty shaken up. Just tell me what happened. Whatever it is, I am sure that it's not that bag."

Maura swallows hard, as if what she's about to say is too much to handle, "I am not a candidate."

"What?" Jane raises an eyebrow.

Maura looks at her, making eye contact once again, "I am not a candidate to donate my kidney," Maura clarifies.

"Why not? I thought that you were a match."

"I am."

"And that it was her best chance," Jane adds.

"It is."

"Then why aren't you a candidate?"

"This morning I went in at six thirty. I had to have lab work drawn, before the procedure."

"That is standard, isn't it?" Jane quizzes.

"Yes," Maura confirms, looking away.

"There was something on the lab work?" Jane infers.

"Yes," Maura confirms.

"Something that prevents you from donating a kidney?"

"Among other things," Maura nods.

"What?"

"Lots of things can prevent someone from donating a kidney. If hemoglobin, or hematocrit are too low, for example. Also, if their glomerular filtration rate isn't adequate. There are many different variables that can prevent someone from donating a kidney."

"What does that mean?"

"Often it means that the candidates kidney is not in good enough shape, to give to someone else."

"There is something wrong with your kidney, too?" Jane wonders.

"No, my kidneys are fine."

"They what's wrong?"

Maura continues on her explanation, despite Jane's question. "Another reason someone might not be able to donate an organ is if they have an infection, or a malignancy."

"You have an infection?"

"No," Maura shakes her head.

"Or a malignancy? You have cancer?"

"No. I don't."

"Maura you're starting to worry me. Instead of telling me all the reasons that someone might not be able to donate an organ, why don't you just tell me, why they won't let you."

"Ok," she agrees numbly.

"So?"

"I..." she pauses.

"You what? Maura are you sick?"

"No, I'm not sick."

"So you're not dying?"

"No."

"So, what is it, then?" Jane begs.
