Thank you to EVERYONE for the great reviews! I love reading them, and some make me laugh :)

Please review if you like this chapter!

I own nothing, only the idea for this story!

No. No, no, no, no, no, no. Simmons thought as she ran into her room and quickly locked the door, and threw herself onto her bed. This can NOT be happening. No, no, no. Fitz...Leo...is my best friend, and we will always be connected that way. But is there more?

The day after quarantine, they had woken in their own beds. Apparently the team had extracted them from their spooning position once they were asleep, and planned on not telling them anything. Well now she understood why.

She didn't know how to handle the situation. Sure, she loved Fitz as her best friend, her brother, but these feelings...could he be her...lover?

She shook away the thought by physically shaking her head, trying to think logically through the situation at hand, but the images of their arms around each other were stuck in her mind, embedded and unable to forget. She could still see how their lips moved so feverishly against one another's, how his arms tightened around her back, how he had pushed her up against the table, with his body pressed up against hers.

Crap.

So much for thinking logically.

Truth was, Simmons wasn't ready to confront her feelings for her best friend. She knew that she loved him, but after the lab incident, it's as if all her subconscious feelings quickly met the surface. She wasn't sure when her feelings changed, or if they ever did. Perhaps she always loved him that way, but they had a platonic relationship for so long, that neither of them expected, or acted on their feelings.

She was awake for the rest of the night.

Fitz, a few doors down, wasn't doing any better.

I just want to walk down the hall, rip open her cabin door, and kiss her, he thought.

No, no, no, I can't do that.

He knew he loved her now. That was apparent. He couldn't stop thinking about her since the lab, and not just because he saw her half naked and she was very pleasing to the eye (although that was a plus), but after the lab, Simmons had started to invade his every thought, every minute of every day. When he woke up, when he went to sleep, while he ate, she even invaded his dreams. This must be what love is like, he wondered. Now it all made sense.

Even though he was sure of his feelings, he couldn't tell her. Not yet. Things had moved quicker than they were supposed to, because of that substance, so he knew they had to take a step back and let it work itself out. He decided he was going to talk to her tomorrow morning –well today, since it was now 4am. Fitz closed his eyes, and tried to sleep, with flashing images of him and Simmons kissing in his dreams.

4 hours later, Fitz was in the lab, exhausted beyond belief, but still there nonetheless. He hadn't slept more than 2 hours last night and was anxious to talk to Simmons.

8:30am, and Simmons wasn't there. 9, 9:30, 10, she still hadn't made an appearance. Fitz was starting to get worried. He walked out of the lab, and made his way towards her cabin, when he ran into Coulson in the hallway.

"Sir, have you seen Simmons?" he asked.

"Yes, she reported that she was sick this morning and needed the day off." Coulson replied.

"Oh...is she ok?" Fitz asked, becoming worried. Was she actually sick? Or did she have a sick feeling in the pit of her stomach because of what had happened between them? If she did, he couldn't blame her. Things were going to be awkward for a while.

"I think so. Does this have anything to do with the video you guys watched last night?" Coulson inquired, trying to read Fitz's facial expression.

"I don't know sir. We didn't really discuss it..." he trailed off, not wanting to admit that they literally ran away from each other, instead of being mature adults and discussing what happened.

"Well, I hope it doesn't affect your work. You're a good team, and I wouldn't want your efficiency being halted. You should go check on her, and whatever this is", he paused, "...sort it out," he said as he walked away, motioning with his head for Fitz to continue on.

Fitz slowly made his way to her cabin, the way he had many times, but it was different this time, he was unsure of what he was going to say to her when he arrived. He quietly knocked on the door in case she was sleeping, when Skye's head popped out.

"Hey Fitz."

"Hey Skye...umm...is Simmons ok?" he asked, his voice etched with worry.

"Well I heard she wasn't feeling well, so I made her some breakfast, she's eating now. I'll give you guys some privacy." She said with a knowing look, and a wink, then walked out the door.

He wondered if Simmons told her anything.

Fitz popped his head through Simmons door, "hey, how are you feeling?"

Simmons had been eating the toast Skye made for her when there was a knock at the door. Skye got up to answer, and she could hear Fitz on the other side.

She knew that he was going to come in and talk about what happened. That was the way Fitz was. He could avoid something for as long as he wanted, but when his mind was made up, he'd do everything in his power to fix it. She loved that about him, the fact that when he was motivated to do something, he would move mountains to achieve it. She wasn't physically sick, she just didn't know how to deal with Fitz today.

I wonder if he has feelings for me?

Fitz popped his head in. "Hey, how are you feeling?"

Simmons shifted awkwardly in bed. "Hey...I'm ok, thanks" she said, looking up, but not really meeting his eyes.

Fitz walked in slowly and sat on the very corner of her bed. "Simmons..."he started, but didn't know what to say.

They looked at each other awkwardly for a moment.

Simmons wanted to get up and kiss him square on the lips, she wanted to tangle her fingers in his hair, but she could barely look at him.

"Look...Simmons...I know what happened last night was awkward." He started, "And that drug really messed with us, so we can't feel guilty about anything in the video." He took a breath, and then continued, "could we just go back to how we were? Just pretend like it didn't happen?" he said, looking up at her with sad eyes. "I miss you...we haven't been ourselves since the lab and it sucks. It really sucks. I feel like I lost my partner. My best partner."

My best partner...I like how that sounds, Simmons thought.

Simmons cracked a small smile, "like it never happened?". She wanted things to go back to normal, where they could be in the same room and not be awkward, but she also wanted to be with him.

In a relationship.

Oh my, did she ever have it bad.

"Like it never happened." She said, and held his hand out to her.

She took his hand, and they did a secret handshake that they made up in S.H.I.E.L.D. academy, something only they knew.

"Although, I'm not sure I can ever forget you trying to do the Macarena. I thought I was a bad dancer, but you take the hat!" she said while giggling slightly.

Fitz breathed a sigh of relief. This was a start.

"I'll have you know, that I am an amazing dancer! My old dance instructor told me so when I was 5..."Fitz stopped abruptly. I did not mean to say that out loud.

"Wait...you were in dance?!"

Fitz gulped awkwardly, face turning red, "Yes, my mom put me in ballet when I was a child."

Simmons had a weird mental image of a grown up Fitz wearing a pink tutu, lab coat, and goggles, and then burst out laughing.

"HEY! IT'S NOT FUNNY," he said while getting off the bed, laughing and making his way towards her. "You know what's coming now!," he said, bringing his hands towards her stomach.

"No Fitz...no tickling, no tickl—" and she burst into a fit of giggles as Fitz started tickling her stomach. This was something they had done for years. When one of them made fun of the other, the other would tickle them as revenge. Sometimes their tickle wars could go on for days, and it had become their thing, but only to them. Other people looked at them weird if they did it in public, and now Simmons knew why...they looked like a couple. It made sense, and she liked it.

"Stop...sto—" Simmons tried to say as Fitz continued attacking her sides. It was just like old times.

She threw her plate of toast off to the side, because she was going to get sweet revenge. She managed to peel her hands off his for a moment to tickle under his arms. At the sudden motion of her hands, Fitz lost his composure and collapsed on top of her. He caught himself before the full amount of his weight fell on her, both his hands on either side of her head and he was just inches from her face. They both immediately stopped laughing, their breath hitched in their throats. They stared intensely into each other's eyes.

Kiss me. Please kiss me, Simmons thought.

Fitz wanted nothing more than to press his lips to her, to feel the warmth of her body against his, to press her down into the mattress, and stay there all with her all day long.

No. You can't do that, you need to be friends, just friends, he thought, as he moved his lips towards her forehead and placed a small kiss upon it.

He moved to get up, when Simmons placed her hand on his cheek, giving it a slight caress. "I missed you too Fitz." She said, as she ran her thumb along the edges of his jaw, his eyes never leaving hers.

It took all of his willpower, but Fitz eventually stood up, took her hand in his and said, "I hope you feel better soon. I should get back to the lab now. Come back to work when you can," and left without another word.

Simmons head fell back on the pillow, with fantasies of what could've happened, dancing behind her eyes.

Back in the lab, Fitz was back to work, feeling much better about the situation. Although he would've liked to end their conversation with a kiss, he knew better.

We just started talking again, we have to get back to normal, he thought.

He worked for a few more hours, beginning to once again focus on the job at hand, when Simmons walked through the lab doors.

His head shot up, looking at her with bright eyes, "Hey! You're back!"

"Yeah, I had some tea and that helped a bit, I'm feeling much better," she said with shining eyes.

Truthfully, even though the video from the previously night was awkward, Simmons just couldn't stand to be away from Fitz any longer, so she sucked up her fear.

"I'm glad," he said, finally feeling like they could be normal again. He wanted nothing more than to be with Simmons.

They worked for a while, trying to perfect the night-night gun, when the PA clicked on.

"Simmons, are you well?" said agent May

"Umm...yes I'm much better...thank you," she said, glancing sideways at Fitz, with a small smile.

"Good, then come to the briefing room, both of you. We have a case to discuss," and she clicked off.

"I wonder what the new case is!" Fitz said excitedly, let's head on up there," he said, and they made their way upstairs to the briefing room.

The team was crowded around the table, waiting for the two as they approached.

"Guys, we have a new mission," Coulson said, "Fitz, Simmons...you're going undercover..."

"Really?" they both said at the same time, clearly shocked.

"As a married couple..." Coulson finished.

They both looked over at each other.

Oh dear.
