I was in a guitar mood when I wrote this chapter as well as a Bee Gees mood, I grew up listening to them. And I was attempting to play one of their songs on my guitar. So then as this happened my brain said "Oh hey, idea!"

Discliaimer: I don't own Teen Wolf nor do I own the characters of Teen Wolf. This is a story people that came from my mind that does not reflect that actions of the real characters.
I also don't own the songs that were used in this chapter, the Bee Gees own all of them.

Summary: The pack finds out what Derek does on Derek Days, which happens to be Derek Law number Six.

Besides Derek Law number four- the sheriff is important- which Stiles hates despite the fact that it revolves around his father, Stiles also doesn't like Derek Law number six. Derek Law number six, Derek Days, means don't bother Derek unless it's an emergency. Stiles knows that Derek needs his space, understands that the lycan needs his space, hell sometimes he feels that he needs it to. A day or two without seeing the lycan, Stiles can stand, three days is pushing it but Stiles' manages. But still, sometimes Derek days are so damn random or out of the blue. The thing that irks Stiles is that he has no idea what Derek does on Derek days. The Alpha was very cryptic about them.

"Stiles, I swear you'll create a hole in the ground if you continue pacing," Scott said amused.

Stiles stopped and glared at his friend, "Not helping."

"Look man, why don't you call him."

"I tried, he won't answer, he either has it off or its on silent or something," Stiles rambled on, "what happens if this is an emergency!"

Scott rolled his eyes, "Stiles, he'll know if it's an emergency, remember we have a system. We call let it ring once, hang up. Do it again, let it ring twice, hang up. Then we text. If all else fails, we sound the alarm."

"Why didn't I think of that!"

"No Stiles!" Scott barked out, "that's ONLY if it's an emergency, Derek made that very clear."

"But this is an emergency."

Scott crossed his arms, "Oh yeah, what's the emergency?"

Stiles huffed, "Well…um I don't know."

"Oh for the love of God," Scott said throwing his arms in the air, "I'm going home, I am not going down with you on this ship."

"Scott!" Stiles called out before his friend could get up and leave

Scott sighed, he looked at his friend, "Stiles, subjection A of Derek Law six says that if you bother him on a Derek Day and it's not an emergency consequences are severe."

Stiles nodded.

"So, you really are going to take that chance."

"I'd just like to know why he's so damn cryptic about these damn Derek Days of his."

Scott raised an eyebrow, "You don't know what he does on these Derek Days?"

Stiles shook his head, "No."

"Huh," Scott said, "hmm interesting."

"Do you know?"

The beta shook his head, "No, I don't either, what do you think he does."

Stiles shrugged, "He's just so damn cryptic about it, I mean, what the hell could you be doing that you have to keep it a secret?"

"Maybe he's embarrassed."

"Derek?"

Scott shrugged, "Hey, he doesn't like talking about his family, maybe this is something that he doesn't like to share."

"So let me get this straight, our Alpha, has Derek Days, to do whatever it is he does because he's embarrassed."

Scott nodded. "Yes."

"What on earth could he be doing!"

Derek Hale was situated at one of the coffee shops in town. This specific coffee shop had an open mic. Open Mic Day meant Derek Day. The Alpha was seated on the stool, one mic placed so he could sing in to the device. The other mic placed in front of his guitar. This was one thing his pack didn't know about him. The lycan secretly loved to play guitar and sing, and he mostly did it when no one was around.

However one day, when he was in said coffee shop, the guitarist who was supposed to play had an accident minutes before he went on stage. Derek didn't know what possessed him to go on the stage but one thing led to another and Derek became a regular performer.

The Alpha's fingers formed chords smoothly, his strumming in a nice mellow pattern. He leaned over singing into the mic.

When I was small and Christmas trees were tall
We used to love while others used to play
Don't ask me why but time has passed us by
Someone else moved in from far away

Now we are tall and Christmas trees are small
And you don't ask the time of day
But you and I, our love will never die
But guess we'll cry come first of May

The lycan faltered for a moment, which went unnoticed from the audience. The door to the shop opened and the familiar scent of members from the Pack hit Derek's senses. He glanced up for a brief second and found himself making eye contact with Allison and Lydia. They waved at him and he simply nodded as he continued on with the song.

The apple tree that grew for you and me
I watched the apples falling one by one
And I recall the moment of them all
The day I kissed your cheek and you were mine

Now we are tall and Christmas trees are small
And you don't ask the time of day
But you and I, our love will never die
Guess we'll cry come first of May

He could hear the girls calling the pack. He inwardly sighed but continued to play.

When I was small and Christmas trees were tall
Do do do do do do do do do
Don't ask me why but time has passed us by
Someone else moved in from far away

Derek hopped off of the stool telling everyone he was taking a break and walked his way towards Lydia and Allison. They stared at each other for a moment. Allison broke the silence, "You play the guitar?"

Derek nodded.

"And you sing?" Lydia asked.

Again Derek nodded.

"That's. Just. Awesome." Lydia and Allison said at the same time.

Derek managed a smile, "Of all places you girls came here?"

"Yeah, well we usually come here on open mic days to see who performs but usually not anyone good."

"I usually come here on those days."

"Why?" Lydia asked.

Derek smirked, "Derek Days."

Allison laughed, "So, this is what you do on Derek Days?"

"Yes."

"Cool."

Derek nodded, "The pack's on their way, aren't they?"

"Yeah, sorry Derek," Lydia said

The Alpha sighed, "It's alright, I'll deal with it," he said as he began walking back towards the stage.

"Where you going?" Allison called out.

"I got two more songs Allison."

Allison called after the lycan, "You're not mad are you?"

Derek sighed as he turned around, "Not mad, just, irritated, you guys weren't supposed to know."

Allison nodded, "Sorry."

"Don't be."

"So can we still stay," Lydia asked.

Derek nodded, "Yeah."

The lycan made his way back to the stage. He apologized to the audience situated himself. Left hand gripping at the neck he began to form the chords to his next song.

I started a joke, which started the whole world crying,
but I didn't see that the joke was on me, oh no.
I started to cry, which started the whole world laughing,
oh, if I'd only seen that the joke was on me.

I looked at the skies, running my hands over my eyes,
and I fell out of bed, hurting my head from things that I'd said.
Til I finally died, which started the whole world living,
oh, if I'd only seen that the joke was on me.

The lycan's ears perked up when he heard the rest of the pack members file in. He looked up for a moment, making eye contact with each one of them, but never breaking levy from his playing.

I looked at the skies, running my hands over my eyes,
and I fell out of bed, hurting my head from things that I'd said.
'Til I finally died, which started the whole world living,
oh, if I'd only seen that the joke was on me.

His strumming stopped and a chorus of claps resounded throughout the room. The lycan eyed his pack in the back, all of them seated at the table their eyes trained on the Alpha. Danny, Scott, Allison, Lydia, Jackson and Stiles all looked at him with smiles on their faces. He bit at his lip, leaning over into the mic the lycan spoke, "This is my last song."

There's a light, a certain kind of light that never shone on me
I want my life to be lived with you, lived with you
There's a way everybody say, to do each and every little thing
But what does it bring, if I ain't got you, ain't got?
Baby

You don't know what it's like, baby
You don't know what it's like
To love somebody, to love somebody
The way I love you

He could hear Jackson reaching across the table and lightly tapping Stiles' hand, "Dude your mate is fucking singing, say something."

"Shh!" Stiles shushed sending the beta a glare

Derek smirked as he looked making eye contact with his mate.

In my brain, I see your face again, I know my frame of mind
You ain't got to be so blind and I'm blind, so, so, so blind
I'm a man, can't you see what I am, I live and I breathe for you
But what good does it do, if I ain't got you, ain't got?
Baby

You don't know what it's like, baby
You don't know what it's like
To love somebody, to love somebody
The way I love you

You don't know what it's like, baby
You don't know what it's like
To love somebody, to love somebody
The way I love you

You don't know what it's like
You don't know what it's like
You don't know what it's like
To love somebody, to love somebody

The last chord of the song resounded within the coffee shop as Derek smiled a thanks into the mic and stood up from his chair. He made his way to his pack, guitar slung on his back by the black guitar strap. He eyed them eye brows raised, "Someone say something," he demanded softly, regretting it immediately as he was met with an onslaught of questions and comments.

"When did you start playing guitar?" Danny shouted

"That was so adorable," Allison squealed.

"Dude you and me need to have a guitar session?" Scott demanded

Lydia was smiling as she said, "Naww Derek that was so damn sweet."

"Why didn't you tell us?" Jackson said as he slammed a hand down on the table.

Stiles remained silent.

"I've been playing for about three years, I'll think about it, thank you Allison and Lydia, and Jackson I didn't tell you guys because, well, its hmmm," the lycan paused "that's a good question, I didn't tell you because at first it was something I did for myself and I didn't want you guys to find out because it's me."

Allison, "Afraid of what we'll think?"

Derek nodded, "Yeah," he breathed, "that and well," the lycan reached up and scratched at the back of his head, "I was a little embarrassed, I mean come on, I'm up there singing and it's not very Derek like."

Danny smirked, "Like right now, you are like out of your element man, why are you feeling so damn nervous, where'd the real Derek go?"

Derek glared as he growled at him a hand reaching over and lightly slapping the younger male on the head. Danny winced, "Never mind, I lied, here's the old Derek."

Derek glanced over at Stiles who still hadn't said anything. Jackson grinned as he nudged Stiles, "Dude I think you broke Stiles, he hasn't said anything since we walked in here."

"Stiles?" Derek said softly reaching a hand out to touch his mate's hand that rested on top of the table.

Stiles bit at his lip and Derek could literally see the gears turning in his mate's head, "You sing!" the brunette cried out, eyes widening.

Derek nodded, "Yeah I do."

"And you play guitar too?"

Derek nodded again.

Stiles grinned, "Holy hell, that's just, damn, hot, fuck."

The Alpha laughed, "Alright, yeah, that makes so much sense."

The brunette stood up placing a kiss on his mate's lips, "Why didn't you tell me?" he whispered.

Derek shrugged, "I don't know, scared I guess."

Stiles raised an eyebrow, "The great Derek Hale, scared?"

"Well Stiles, I sing and play guitar, it doesn't seem very Derek like."

The brunette bit at his lip, "Yeah neither is Derek Law number two."

The lycan rolled his eyes, "Shut up," he mumbled.

"Do you only play on Derek Days?" Stiles asked.

Derek nodded, "Yeah, this is what I do on Derek Days."

Scott spoke up, "Why so secretive about it?"

The Alpha shrugged. He breathed deeply, "You guys are my pack, and I guess the reason I didn't tell you is I needed something, something that's just for me you know something to get away from everything for a while."

"We understand," Allison said.

Everyone else nodded in agreement. Derek turned his attention to Stiles, "Sty, say something."

"Will you make an exception and play for me sometime, other than on a Derek day?"

"For you I will," Derek answered as he placed a gentle kiss on the brunette's forehead. The Alpha then looked towards the pack, "Hey, just because you guys know about what I do on Derek Day's doesn't mean you can go and break Derek Law number six."

"We know not to bother you," Jackson said waving him off.

Derek glared, "Yes and that means physically as well."

Danny threw his arms in the air, "Really man, we can't come here and watch you."

"Oh come on Der," Scott said.

The Alpha glared at him, a threatening growl emitting from his chest. "Ooops my bad sorry," Scott rushed out.

Allison grinned, "Oooh Scott, I can't believe you just broke Derek law number ten."

Scott threw his mate a look, "Really Allison."

Lydia laughed, "I know Scott and yesterday you also broke Derek law number five as well."

Danny and Jackson were laughing as well, "He has a bad memory."

"Okay, can we please just get over the fact that I've broken two laws already?"

"Naw," everyone said in unison

Derek rolled his eyes, "See, this is why I have Derek Law number six, when you guys argue and tease each other, damn sometimes it drives me off the wall."

"So that's a no to us being here then?" Stiles asked, staring at Derek with his puppy dog eyes

The lycan let out huff. Stiles was now grinning, "Cause technically if you look at it, Derek law number six is, Derek Days means don't' bother Derek unless it's an emergency. And us being here isn't really bothering you, we're just watching you."

Derek looked up then down at his mate. The lycan bit at his lip, eye brows scrunching as he processed what Stiles just said. True, they weren't technically bothering him, just watching him. He really didn't think this law through, he should've made it so that they couldn't bother him at all but then again if something happened and he wasn't there he'd be letting the pack down. "Alright," he said, "but if you guys start becoming a distraction then you won't be allowed to watch at all."

"Deal," everyone said

The Alpha rolled his eyes. The lycan looked down at the brunette, he placed a gentle Stiles lips and, "What's up Sty?" he asked softly, immediately noticing that the younger male had something on his mind.

"You play guitar," Stiles whispered.

Derek laughed lightly, "Yeah I got that."

"And you sing," Stiles whispered again

Derek nodded, "Yes, yes I do."

"I just, my mind, I'm just,-it just, damn, I can't wrap my mind around that, the fact that you play guitar and sing, it just throws me."

"Still love me?" Derek asked.

Stiles looked taken back, "Of course I do," he whispered, "not going to change, in fact I think I love you even more."

The Alpha but couldn't help the grin that escaped him. Stiles was looking at him, a smile on his face. Derek could feel a happiness and adoration coming off of his mate. The lycan kissed Stiles softly, "I love you," he mumbled happily.

Thoughts?

I liked the idea of Derek playing guitar. I just did.
Like how I made him "smoke cigarettes" in my story I Don't Feel it Anymore.
Besides, this fanfiction people, I can make Derek jump off a cliff if I wanted (but I won't do that).

The songs I used were:

The First of May by the Bee Gees
I Started a Joke by the Bee Gees
To Love Somebody by the Bee Gees

Awesome songs!
Have a nice day or night or afternoon.
