This is the sixth story in my personal trainer AU verse. Reading the prequels would really help to understand this. They are:

Anything Can Happen
Awkward Encounters
Movie Night
Clingy Exes and Devious Plans
A Sweet Treat (which is admittedly not really necessary as it's basically shameless smut)

If you haven't read them, then basically Sam is a personal trainer and Gabe runs a sweet shop. They started a relationship after Gabe propositioned Sam at work. They've been dating for a while, but Sam's still quite closed about his personal life, especially college – and he ran into an ex, Ruby, a while ago and panicked about it, for reasons that Gabe doesn't know.

This should be a two-shot – most of the explaining stuff will happen in the next chapter. I hope you enjoy it!

Do I need a disclaimer? Everyone knows I don't own the characters or the show... (although I wish I did).

There were things about Sam that Gabriel still didn't know.

He didn't know why Sam arranged to meet up with Dean every fortnight even if he was super busy and ought to be spending the time doing something else. He didn't know how close the brother had once been, and how they were slowly trying to mend the fractures in their relationship. He didn't know that Dean had raised Sam after the death of his dad. Sure, he knew John had died when Sam was a teen, and Mary when he was a baby, but he didn't know the details. He had never pushed for them. It was nice, not being forced, but Sam didn't know how to bring it up on his own.

Gabriel didn't know about Sam's college years. The incident with Ruby had given him a glimpse, but nothing concrete. Sam was even more reluctant to talk about that than he was about Dean. True, the two were irrevocably linked, but the Ruby days were far worse than family drama. The scandals of Sam's past could fill a whole library of books. He would never be able to explain them all, even if he wanted to.

There were smaller things too – Sam had never told Gabe about his wish for a dog, or the brochure about Spain he kept tucked under the bed in hopes he could go someday. He knew that Sam liked to be dominant in bed and struggled with submission, but he didn't know that Sam also liked pain with his pleasure. (That, again, delved to close to the Ruby-era for Sam's comfort). It was trivial, really, and Sam expected that most partners had secrets, but as time went by, he couldn't help but think that there was just too much that Gabe didn't know.

He had been on edge all week. The city's half-marathon was a week and a half away, and work was teeming with people who were competing in it. Sam could barely catch a break, working almost solidly from seven in the morning until eight at night and only just dragging himself home before collapsing to repeat the cycle again. He worked six days a week and used the spare day to improve his own fitness and alternately meet up with Gabe and Dean. He knew that Gabe was feeling a bit ignored, but he had so much going on that his boyfriend's feelings ended up on the wayside.

He was therefore rather surprised when he collapsed on the couch on Friday night only to hear the doorbell ring.

Dragging himself up, Sam idly wondered if he was expecting a late delivery. He grabbed his wallet just in case, opening the door and blinking in shock at the sight of Gabriel standing there.

"Gabe!"

"Hey, Sasquatch. Feels like we haven't had any time together in ages."

Sam opened his mouth to apologise, but Gabe waved him off.

"Don't worry, I get it. I've seen you at work. You'd work yourself to death if you didn't have Dean-o and I. Can I come in? I'm freezing my balls off out here and they're definitely my best asset."

Honestly, Sam was too tired to want to spend any time with Gabe. It wasn't Gabe's fault, it was his, but he doubted he could stay awake long enough for a proper conversation. But he had been neglecting Gabe recently, and he was feeling guilty over all the secrets he kept, so he waved Gabe in. Shutting the door, Sam wondered how best to disguise his sleepy state.

"You got any beer?"

One advantage to dating Gabriel was he talked enough for two. Sam had a feeling that the guy would probably carry on a conversation with himself if Sam fell asleep.

"It's in the garage where it normally is. Do you want me to get it?"

"Nahh, don't worry. I want to talk to you, not have you fall asleep on the garage floor."

Sam blushed. He had forgotten how perceptive Gabe was.

Gabe plopped himself down on the couch and Sam followed, slightly unsure what to say.

Gabe gave him a strange look. "Come here," He offered, holding out his arms.

Sam felt immeasurably grateful as he melted into Gabriel's embrace. He wasn't normally this out of it, it had just been a really bad week. Stress had a tendency to fry his brain. It was why he had switched out of pre-Law, amongst other things...

'Don't go there!' His brain screamed at him, but Sam's thoughts were already hitting overdrive at the memories of college.

"Woah, Samalam, you in there? Jeez, if I didn't know better I'd say you were high."

Sam tensed.

His rational mind knew that Gabe wasn't psychic. But Sam was running on energy drinks, adrenaline and sleep deprivation. His rational mind wasn't as in control as it should have been. So he couldn't stop the panicked shudder that wracked his body at Gabe's words.

"Sammy? Sam? What's wrong? Come on, talk to me."

"It's nothing." Sam was proud of how normal the words sounded when he finally got them out.

"Sam, this is not nothing. Look at me."

Sam looked up and met the worried caramel eyes of his boyfriend. He sighed, moving back and out of Gabe's embrace. He didn't deserve this. If he fucked this up it was entirely his fault.

"Don't worry, Gabe. I'm fine. Just not getting enough sleep."

"No shit Sherlock."

Sam cracked a smile.

"But I'm not just talking about your out-of-it attitude. What was that a moment ago? Did I say something?"

"No." Sam replied too quickly, but now was not the time for this. "It was nothing. I'm just tired and stressed and I feel like a shitty boyfriend because I've been ignoring you. And I want to talk to you and cuddle and fuck on the couch like we normally do, but I really need to lie down and pass out. I'm sorry. It's not you."

Gabe shifted closer, curling an arm around Sam's shoulders and pressing a kiss into his neck.

"Chill, Sammy. It's fine. Let's go up to bed and sleep and we can talk about this in the morning."

"I have work."

"You have bags under your eyes and smell like death, no offence. You've been working too much. Your job's demanding, you can't physically push yourself to do such intensive regular shifts. Just call in and take the morning off."

Gabriel was right and Sam knew it. As a personal trainer, he couldn't work twelve hours a day six days a week. Most office workers couldn't do that, and his job involved serious exercise sometimes. Not to mention he was planning on running the half-marathon with most of his clients. But he didn't want to tell his boss no in case he got fired – his job was precarious enough as it was.

Not that Gabe knew that.

"Ok." Sam agreed. "I'll go in for afternoon shift."

He stood up and stretched, before glancing back at Gabe.

"You don't have-"

"I know I don't have to stay. I want to stay. Now go to bed mister before I have to drag your muscular ass up the stairs."

A weak laugh tore itself from Sam's throat and he smiled, kissing Gabe briefly before heading upstairs. Gabe was amazing. That was why he had to know everything – someone as good as him deserved to know.

But would he still want Sam when he knew all about the past?
