The down fall of Stiles' old phone is something that doesn't get talked about much. It may have happened at the gay bar. Stile might just have been talking on it while taking a piss and accidentally dropped it in the urinal. Okay so Scott will probably point out he was definitely on the phone, since he was bragging about what a good dancer he was becoming and how jealous Derek was about guys trying to buy him drinks, but we digress. He may just have instinctively bent over to fish it out of the toilet and had a moment where he was saying "Come on, come on, come to mama" a few times. But he was definitely talking to the phone NOT that strange guy who walked into the bathroom who took Stiles bent over position and words to mean something entirely different then what had been meant. That Stiles had at that moment managed to fish the phone out and turned his head to see who the f had decided to try and grind up on him and Derek had walked in to see what was taking Stiles so long only to find his boyfriend wrapped in some other guy's arms and Stiles freaking out. Stiles denies absolutely any said freaking out. He swears he was very calmly asking the guy to let him go as he hit him over the head with his pee phone.
So Derek might have just over reacted just a little bit and grabbed the guy by the neck and thrown him against the wall and Stiles might have just flailed a lot losing his balance at the abrupt motion of Derek pulling the guy off of him and on the toilet water that had dripped on the floor. His wet phone might have just gone flying out of his hand and smashed against the wall.
Stiles, though grateful on some level for Derek's interference had, had still given him a hard time about his jealousy and in his opinion over reaction and for breaking his phone (he of course did not tell anyone about the phone dunking because well free phone reasons...). So his super hot boyfriend bought him a new phone and because he is also an awesome sugar daddy who maybe felt a little guilty about being over protective, he bought Stiles an IPhone.
Stiles loved having the IPhone because it allowed he and Derek to use FaceTime (since he insisted Derek update his phone too). Stiles loved FaceTime. He would call Derek and Derek would give him a frowny look and say "Stiles, we're in the middle of a pack meeting." Or "Stiles it's the full moon, stop calling." Or his favourite "Stiles it's 3 a.m. go to sleep!" But you see When he called and called Derek would get frustrated and Stiles could see by his facial expressions just how much to press him until Derek was mad enough to climb through Stiles' window to tell him to stop. Derek couldn't just shut off his phone because of the pack and he couldn't ignore Stiles' call because It could conceivable be an emergency, it is Stiles after all. But when the werewolf came through the bedroom window, Stiles got what he really wanted, which is real face time. So for once, Stiles was going to call this one a draw.
I know it's been a while, but I have been sick. I have a few chapters I am in the process of working on, but wanted to give you all just a little taste for being so patient.
