Spinning around, Batman knocked the offender away. It slid to a halt when it hit the wall. He grabbed a batarang inching closer to the creature. Once he got closer he found that the creature was a big black wolf and it looked hurt. Slowly inching closer, Batman surveyed the wolf it was having trouble breathing and it seemed to be bleeding. As he got closer the wolf got more aggravated, but once he was a few feet from it it started whining. Alfred seemed to not be worried about the wolf because after he fixed the oxygen mask on Stiles, he rushed over to the wolf. Bruce wasn't paying attention so Alfred ended up rounding him and kneeling by the wolf before Bruce or Batman could stop him.
As soon as Alfred was kneeling down he started yelling orders. "Bruce I need a med kit," he said the he turned his attention back to the wolf, "I need you to shift I have to assess the damage." The wolf whine but started to shift. One minute there was a wolf on his cave floor and the next there was a naked human male. He must have been standing there for too long because the next thing he knew he was being yelled at again.
It only took a short time for Alfred to patch up Derek, (Batman remembered the man from earlier), the boys were off trying to figure out what happened and how to get out of the cave.
Thank god Derek was the same size as Bruce, so at least Derek didn't have to go around naked. The only real option to get out of the cave was through the secret entrance. Stiles gained conscious when they were loading him into the batmobile. If he wasn't on heavy pain killers he probable would have squeaked in delight but he was just speechless. The batmobile only seated two so Batman had to make multiple trips or Alfred could that the backup batmobile. So now both Alfred and Batman were driving out of the cave with their wounded passengers. It only took them five minutes to get into the middle of Gotham. Batman dropped Stiles off in a remote location and Alfred did the same for Derek. He asked them if they could get themselves out of town, nodding Derek carried his wounded mate to the parked car set him on the hood while he hot wired it.
As soon as Batman and Alfred dropped them off the took off to try and put Gotham back together. Derek got the car running and he almost made it out of town when he got ambushed by some clown freaks again. Stiles regained consciousness as the people were dragging Derek through the windshield. Stiles may be human but when you threaten his mate he goes super hulk. Stiles saw a crow bar on the floor next to him, he got out of the car swinging. He took one guy out and knocked on back, Derek was holding his own against the other three. They must have made enough noise because others started coming towards them. They must have been overwhelmed because a dark figure showed up. Once the clowns and hoodlums were knocked out, Stiles got a look at the figure before he flew away. The only thing he could tell was the blue bird/bat thing on his chest as he zipped away. Stiles was in awe, not only did he find out that Batman was real but now he actually saw NightWing, he was excited. When he went to squall to Derek he noticed more people coming towards them.
By sun rise Derek and Stiles finally made it out of Gotham. They were headed to New York city towards their hotel. Of course they checked on late by a couple of days but they finally got there. Despite the injuries and tiredness Derek and Stiles took full advantage of the time they had left in New York. They were only scheduled to have the hotel till Saturday but they got it till monday, they had extra time because now they didn't have to drive back.
Once they made it home they slept for a full day. The rest of the gang and the Sheriff asked questions and of course Stiles bragged about Batman and NightWing. Scott was envious and jealous of the trip he told Stiles that they should go to Gotham to meet him.
Over the next few months Stiles spent extensive time researching Batman and the clan, he tried to figure out who was under the mask. Stiles would even take his research to bed, Derek was getting fed up with it. Four months after the Gotham incident, Derek had enough. He was in bed with his mate trying to be sexy but Stiles wasn't paying attention. Finally Derek took the book out of Stiles's hand throwing it across he pinned Stiles to the bed and attacked his neck.
Stiles didn't say much during sex expect you know 'Oh god, right there,' and 'Derek.' When they were finished Derek was enjoying the afterglow but it only lasted a few minutes because Stiles started with the research again. Growling Derek said, " if I tell you who Batman is will you stop with this bullshit?"Staring wide eyed and mouth opened, Stiles nodded. Sighing Derek told him that he already met him at the confused look, Derek explained that Bruce Wayne was Batman. Grinning Stiles replied, "that makes sense" rolled over and fell asleep.
The next morning Stiles asked how Derek knew that Wayne was Bats, Derek explained about the scent because Alfred insisted that he wear clothes and that the cave was under his house. That was the last that they spoke of it well until until Bruce was having a party then Stiles insisted on going but Derek usually distracted him with sex.
