It shouldn't have surprised him, really. He had been pushing off his own breakdown to deal with Mac's, and the moments when it was quiet and he had time to think about it, he pushed it out of his mind and poured himself a drink of Scotch.

The weekend went by too quickly, much too quickly for Will's liking. He wanted to stay holed up in their apartment, but he knew that Mac was antsy to get back to work, get back to normal, and he was not going to deny her anything at the moment.

Habib had prescribed her something to help her sleep, and it had helped with the nightmares, for which Will was thankful. He couldn't handle it. Not when she woke up, terrified and confused, her eyes darting around their dark bedroom and her pulse racing.

"I'm here, I'm here, you're okay," he would repeat until she calmed down, running a soothing hand up and down her back.

But the sleeping pills had helped. Immensely. She could sleep, he could sleep, and by Monday she was ready to go back out into the real world.

The alarm went off Monday and Mac groaned, rolling over into her pillow.

"You were the one who wanted to go back to work," Will reminded as he patted her blanketed back as he rolled out of bed to start the coffee.

"I forgot about the waking up part," Mac mumbled. "It really sucks." Will chuckles, leaning down to drop a kiss on her hair, before going to get ready.

When they climb into the car, Lonny turns around and wags a finger at both of them.

"No stops!" He scolds. "We're going straight to the office."

"Won't hear any complaints from back here," Will mutters. Mac doesn't say anything, just twines her fingers through Will's and drops her head to his shoulder.

She had already told Jim that she didn't want her return to the office to be a big deal, and while people came over to give her a hug and welcome her back, it was pretty low key. Will follows her into her office and settles down into the chair across from her desk and she raises an eyebrow in his direction.

"Are you going to sit there all day?" She asks amused.

"Maybe," he shrugs.

"I'm okay, Will, I'm not going to leave this office. Trust me, I have plenty to do," she reassures him, and she crosses from behind the desk and leans down to place a soft kiss on his lips.

"I know," he replies, and he does, he knows that she's okay and that she'll just be in the office next to his, but since she walked out of that bank she's not been more than three feet away from him at any given moment, and he's not quite ready to let her out of his sight. She gives him one more kiss and then points a finger to the door.

"Go, go to work, Will," she instructs, and he begrudgingly follows her request, turning to look at her as she settled in at her desk, and wondering how the hell he would have kept going if something would have happened to her.

The show goes off without a hitch, and Will thinks all in all it's been a pretty good day. They get back to the apartment and Mac is exhausted and her arm aches, so she gives Will a goodnight kiss, and climbs into bed. He promises her he'll be right behind, but pours himself a drink and settles in his chair.

He doesn't realize he's fallen asleep out there until he hears a scream rip through the apartment, and his heart is racing as he jumps to his feet, rushing back to their bedroom where Mac is thrashing around in the covers.

"No, no, no, no," she repeats, and he realizes, belatedly, that she had been too exhausted to remember to take a sleeping pill. He gently shakes her awake, and pushes a piece of sweaty hair from her forehead.

"You're okay," he tries, and every other time that has been enough to wake her up, to make her realize where she is and that's she safe. This time is different though, and it's enough to send Will into an absolute state of panic. "Mac? Sweetheart? Wake up. Mac, you need to wake up." His voice holds an edge of terror as she shifts, but her eyes remain firmly shut. "Mackenzie!" He's practically yelling now, gripping her arm tightly, too tightly probably, but she won't wake up and he doesn't know what to do. When he's about to pull his phone and call Habib, or someone, he doesn't care who at this point, her eyes fly open and she bolts awake, her body trembling.

"Oh God," she says, her hand flying to her mouth. "That was the worst one yet."

"You're okay," it's a stupid thing to say, but he's not sure what else to say, so he just keeps repeating it. "You're okay. What can I do to help Mac?" His voice sounds so broken, and she tugs on his hand.

"Just hold me?" And he strips down to just a boxer and a t-shirt, crawling under the covers and pulling her body to his. He skims a hand down her arm and presses a kiss to her bare shoulder.

"Go to sleep, sweetheart," he whispers. "I'm right here."

Two hours later, it's Will who wakes with a nightmare, a scream caught in his throat. Mac blinks sleepily at him, her voice drowsy with sleep when she notes,

"We're quite the pair, aren't we?" He doesn't answer, rubbing a hand over his face. "Want to tell me what it was about?" He shakes his head at first, because he can't dislodge the image of Mackenzie bleeding to death on the bank floor, her eyes staring blankly. "It might help if you tell me about it," she tries again.

"You were in the bank," he swallows hard. "You, uh, you didn't make it out." And his voice breaks on the last word and she's crawling into his lap, her arms snaking around his neck as he buries his head in her hair, breathing in the smell of her. He finally begins to cry, hot tears rolling down his cheeks and dripping into her hair, and she doesn't say a word, just holds him tight.

She doesn't say anything, because she's not sure what she's supposed to say. She doesn't say she's okay, because he knows that rationally, and it's not completely true anyway. She's okay physically, but she's a long way from being okay mentally, and both of them know that. She doesn't say that it's all right, because it's really not fucking all right.

"I was so fucking scared," his voice trembles. "You have no idea. You have no idea. If you hadn't made it out…if you didn't…I wouldn't have…I wouldn't have made it, Mac. I wouldn't have."

"Don't say that," she whispers.

"I know what it's like to live without you, and it's fucking awful. But at least then I knew if I got my head out of my ass I could call you up, I could talk to you. You were God knows where, but you were walking and talking and alive. I can't go back to that, sweetheart, I can't live without you again. When you were in that bank all I kept thinking was, that's my whole life in there. That's everything. You're the only thing that matters. The only thing."

"Will," he realizes that she's crying now too, her small frame shaking with the sobs and he presses kisses into her hair to try to get her to stop. She's not sure what to say to that. She settles on, "I love you," and he tilts her chin up and presses a fierce kiss to her lips.

"I love you, so much," he tells her.

"I don't think I'm going to be able to sleep tonight," Mac admits, but she still climbs out of Will's lap, reaching for his hand as she slides back under the covers. He slides down, their noses inches apart, and tucks a strand of hair behind her ear. But soon, Will's arm warm and safe around her, and his breathing even in her ear, she's drifting off to sleep, and luckily, both of them sleep soundly through the rest of the night.
