Dinner after Stiles went up stairs consisted of 30 of discussion of the problem of what sounded like a hellhound attacking their new foster son's best friend, which he hoped would be more sensible in the morning. After 30 minutes he had to call it a night. Cas took the dishes and he and Sam went upstairs. He stopped in to check on Stiles.

"Hey. What's up?" Stiles seemed to be hiding something, but he figured it was just that he wasn't really doing homework, which Dean already assumed.

"Hey. We're all heading to bed. You know where we are." Stiles smiled at him and nodded.

"Sleep well. If I stay up I'll make sure there's coffee made." Dean smiled.

"Cas and Sam should be up in the morning to keep you company. Sweet dreams." Dean took a quick shower and brushed his teeth before going back in his and Cas' bedroom and turning off the lights. He stood at the window, first to check that it was still salted, but then to admire the night. Before he had time to enjoy it he saw something moving in the dark and then heard a thud on the roof of the back porch. He looked out only to barely see something slip into Stiles' window. Dean quickly grabbed his pistol out of his bedside table.

"What's wrong Dean?" Cas' voice got rougher when he was nervous or worried or confused. It was definitely rough now.

"Nothing. Stay here. I'll take care of it." As Dean went down the hall, Sam opened his door and looked down the hall and back at him, asking if he needed back up, but Dean gestured for Sam to stay where he was. As he approached Stiles door Dean swore he heard whispers. Dean opened the door and aimed his gun, scaring Stiles and surprising what seemed to be his guest.

"Oh, god! He's not breaking in, don't shoot!" Dean lowered his weapon and gave an angry sigh.

"I'm not going to shoot him! Yet, anyway. Who the hell is he and why is he here?!"

"Th-This is Derek Hale and he's here to talk. Just talk." Dean rubbed the bridge of his nose between his fingers.

"Stiles, Why is he breaking in, in the middle of the night, to talk?"

"Uh, could I please talk to you about this in the hall?" Dean was tempted to say no and just kick the guy out, but Stiles' pleading tone got to him a bit. He sighed and pulled Stiles into the hall and closed the bedroom door. "To start, don't hold this against Derek. I told him to sneak in."

"M-hm. Why?"

"Because it's late and I didn't think you'd want me having some guy you don't know coming over in the middle of the night after Sunday. You and Cas have been freaked out all week."

"Because giving us a heart attack is such a better option? We're worried about you, Stiles. Sue us."

"I'm sorry; I just didn't think you'd find out honestly."

"And not to mention having some guy over in the middle of the night without us knowing, how well do you even know this guy? He could be a serial killer or a rapist or a cornucopia of things you could not possibly imagine!"

"He's an acquaintance. His family died when he was young. I ran into him today and we got to talking. We were texting after dinner and he told me his sister died just recently so and he said he wanted to talk, so I invited him over." Dean sighed feeling a bit guilty.

"This time I'll let you get away with it. Next time you want to have someone over passed ten, tell us. I don't care what entrance they use, but I'd prefer the front door. I honestly don't wanna see him here in the morning, so make sure he's out of here by one." Dean hesitantly gave Stiles a quick hug. After pulling away he pulled out the sternest voice he could muster. "And if you scare me like that again, I will nail your window shut and you will be home schooled until you go to college, do you understand me boy?" Stiles nodded curtly.

"Yes, sir. Sorry." Dean nodded back and tried not to smile.

"Good. I'm going to bed. If he's a serial killer, yell for Sammy. He's a light sleeper. If he's a rapist, there's a shotgun in your closet." Dean walked calmly back to bed. Cas was pacing. "Our kid just had a boy sneak into his room." Dean hugged the angel from behind.

"Normally that would mean the boy is his romantic interest."

"Yep… Seems like it."

"Shouldn't we meet this boy?" Cas leaned back into him gently. Dean rested his head on Cas' shoulder.

"No, not yet. Stiles said the guy's here to talk and I believe it. So, we wait for Stiles to want us to meet him. They may not even get serious."

"Did the boy seem nice?"

"God no. He was wearing jeans, a leather jacket, and I think high tops. He was my height and I'd be surprised if he was more than 10 years younger than me. I'm pretty sure I smelled booze. I wanted to shoot the guy." Dean sighed. "I probably would have if I'd known Stiles for more than a week."

"If it means anything, I firmly believe that makes you a good father…" Dean smiled and kissed Cas' cheek.

"I really love you…" Dean turned for the door again. "I think I'm going to go bust the door in again just to scare him enough to keep his hands off Stiles for the night." Cas chortled and hugged him from behind, keeping him there with his angel.
