Stiles want stupid, he knew that giving his phone number to one of his students was a bad idea. That apparently hadn't stopped him. He also knew that if Derek texted him with anything that wasn't relevant to class or his out of class issues that he should ignore him.

He didn't.

To Derek

From Derek
like anyone could do that.

Stiles stopped replying at times like these. Whenever the flirty undertones took over the conversation and filled him with guilt. Derek was still a student as much as he might want otherwise. He opted out of answering, at least for a few hours.

"You're going to get fired." Lydia said plopping down beside him with a piece of pie and a smirk.

"There's nothing illegal about texting."

"If you're smiling that much I might beg to differ." she replied waving her fork at him. "Child pornography Stiles. Very illegal."

Stiles snorted, "unless talking about Jensen Ackles cheekbones became porn without my knowledge, I am partaking in no such thing." he replies dipping his finger into the whipped cream atop her pie and licking it off with a devilish smile.

"How long have you been texting him?" Lydia asked shooing his hand away when he went for another bite.

"Uh... Two months"

Lydia shot him a glare. "You are hooked Stiles." she frowned. "Just be careful, you know what hale men are like."

Stiles knew he shouldn't but he got defensive. "Derek... Lydia Derek's not like that. He isn't going to hurt me; I'm the one being a pedophile here."

"Peter didn't seem like the type to tie you up and rape you either Stiles but he did. I'm just telling you to be careful."

"I will be." Stiles replied picking up his phone as it buzzed.

From Derek
I just wanted to say thanks

To Derek
for what?

From Derek
Everything you've done, just wanted you to know I appreciate it.

Stiles smiled.

To Derek
that's what I'm here for.

From Derek
I'm sorry

Stiles' heart dropped to his stomach. This was all starting to sound wrong, to sound eerily familiar to the messages he had sent Lydia when everything started going to shit. His fiancé had dumped him, his dad had gotten sick, Scott had left him for Allison again and Stiles, he was low. Derek's words were beginning to sound like his suicide note.

"LYDIA HELP ME!" He exclaimed grabbing his coat. "I need Derek hale's address right now!" Lydia walked back into the room,

"Stiles if you go to that boys. House you'll be fired"

Stiles flailed his hands trying to work his way into his shoes.

"Lydia Annabethe Martin Derek is going to kill himself if you don't give me the god damn street address right now so help me god"

Lydia's face dropped, " oh god of course yeah. "She said rushing to her computer to pull up the student files. "1888 sycamore lane he lives with..." Lydia pauses,
face contorting in pain. "oh my god Stiles he lives with Kate and Peter Hale."
