The tires of her SUV crunch against gravel. JJ peers up at the rearview mirror to see Henry staring out the window, long blond hair falling over his face. He still reminds her of Will, but it hurts less now. The wound in her heart is no longer aching. It's like something is patching it up and letting it heal.

The car jolts to a stop in front of his house. The house he and his girlfriend got together. But somehow, that hurts less, too. From what she's heard, Will's girlfriend seems perfectly nice, and Henry likes her a lot. What's the harm in Henry having another adult in his life who cares about him?

"Alright, honey, you ready?" JJ asks quietly, trying to hide the sadness in her voice. She may not miss Will the same way anymore, but dropping off Henry never ceases to cause her pain.

Henry nods. "Can't you stay too, mommy? We can all play together."

JJ presses her lips together. "Oh, you and daddy and Allie will have so much fun together. You'll forget you miss me in a minute. Don't worry." JJ takes a deep breath. "Let me walk you up."

It's been a long time since she's seen Will. She almost always drops Henry off at school for Will to pick him up on his days, and vice versa on hers. But she's ready now. To meet his girlfriend. The other woman who spends so much time with Henry. The woman who lives with her ex-husband. Who will probably end up calling JJ's child her stepson. Okay, JJ thinks, maybe it still hurts a little.

Will and Allie open the door together, and Will picks up Henry in a big hug. Allie gives him a kiss on the head, which he rubs off playfully. It's his favorite game these days: get a kiss, rub it away. It makes JJ think he's growing up too quickly.

"Hi, Jennifer! It's so nice to meet you," Allie says, and smiles. Her hair is blonde, just like JJ's. Her eyes are blue, just like JJ's. God, maybe this is just a rebound.

"It's nice to meet you, I've heard good things," JJ says, smiling politely.

"Oh, Henry sure is a talker, isn't he?" Allie rubs Henry's head, and he laughs. A quick pain slices through JJ's heart.

"Allie, can you let me talk to JJ for a second? Why don't you take Henry," Will says softly, his southern accent rolling through his lips.

Allie smiles awkwardly, looking between her boyfriend and his ex-wife. Will places Henry on the ground, and JJ wraps him into the last hug she'll get for several days. She holds him close, breathing deeply, then stands up and nods. Allie gives her a smile and leads Henry, waving goodbye to JJ, away into the house. JJ waves back and looks at Will.

"How have you-"

"We need to talk," Will interrupts, and JJ sighs. It's still adversarial with him. How long will he be mad at her? He's the one who cheated, and she still gave him as much time with Henry as he wanted. He's a bad husband, not a bad father, and JJ will always know that. But she still wishes he would let the anger and the grudge simmer down and just be a kind coparent. It's all she's been trying to do.

"What do you want, Will?" JJ crosses her arms.

"Henry's been asking," Will replies, "about us. He asks why we're not together anymore, he asks if Allie's his new mommy. I just think we should agree on what to tell him so he's not confused," he slurs slowly.

JJ exhales quickly and stands up straighter. "Why not just tell him the truth? His dad cheated on his mom." She bites her words.

"That isn't the whole truth, JJ."

"Oh, yeah? And what is?"

"You know what I'm talking about. You never felt the way I did. You were always with someone else in your head. Always at work-"

"That's my job!" JJ exclaims, exasperated.

"It's not your job to always stay late when Emily does. I've called for you, you know. They told me you stayed late with Emily. They told me you and Emily were working on something. At some point, JJ, it finally clicked. You were never in love with me because you were in love with another woman the whole time. Is that what you want me to tell our son?"

JJ's heart stops. She tries to breathe, but she can't force air in or out of her lungs. She just stares at Will, unable to speak, until she finally chokes out the last thing she can think to say.

"You are the one who betrayed our marriage, Will, not me. Tell him whatever the hell you want. I've never said a bad word about you to him, and I never will. But I'm not asking you to do the same."

JJ takes off, driving down the block. She pulls over as soon as she's out of sight from the house and starts to sob, her forehead leaning against the steering wheel. He knew. The whole time, he knew. And he was right. All those nights when she preferred Emily over her husband, all those times she offered to help her with something she didn't need her help with, it wasn't friendship. It was love. The kind she never felt with Will. The kind of love that's all-consuming. JJ felt the love that made her choose it over everything.

JJ swipes at her eyes when her phone beeps. Garcia needs her to come in. She checks her face in the mirror, patting her cheeks gently, erasing all physical memories of her sobs. She takes a deep breath and starts for the BAU.

Everyone is already seated at the round table when she arrives. Hotch looks concerned, as always, standing above everyone. Garcia darts her head around, confused. JJ wonders what the case is, considering the fact that Hotch called the meeting, not her. She didn't know of any new cases. If they went to Hotch over her, it must be really important. She sits next to Garcia.

Morgan looks around. "Has anyone seen Emily?"

JJ squints. "No, not since-"

"Since you and her wandered away by yourselves at the Commemoration? What was up with that?" Penelope elbows JJ gently, and JJ blushes furiously. She nudges Penelope as a warning, still trying to avoid hinting that she and Emily are. . . well, what even are we? JJ wonders.

Suddenly, each cell phone in the room blares a text message alert. They all look at each other cautiously, and Hotch nods, all of them pulling out their phones to check.

JJ's heart stops. Her breath catches. Everyone stays silent for a moment, staring at the message. JJ feels the blood rush through her veins. She feels her heart pumping again, aggressively and quickly. Adrenaline cycles through her, bolts of energy and anger shooting each other inside, telling her to fight. JJ reads the message again.

We have Emily Prentiss. She has 24 hours to live.
