Review maybe? Only nice ones pretty please. I wrote this at like 3 a.m. Don't judge.

Stiles remembers the first time they called him mom. Actually, it was Isaac who said it first. It was the night after the full moon and they had just woken up after falling asleep before dawn. Stiles was in the kitchen cooking them all breakfast as they trudged in single file. Isaac, Erica, Boyd, Scott, Jackson, Lydia and last but not least, Derek. "Thanks mom." Isaac murmured as Stiles set his plate full of food in front of him. No one even looked up from their food as it was said so Stiles just shrugged and went back to the oven. 'He must be really tired to have said that' Stiles thought to himself.

The second time was on at a pack movie night. Stiles was in the kitchen popping the popcorn when a cry came from the living room. "MOM!" Erica called, "They won't stop fighting over what movie to watch!" Stiles hurried into the living room before anyone could wolf out. Lydia, Jackson and Scott were all fighting over what movie to watch. Lydia wanted to watch The Notebook. Jackson was insisting they watch The Dark Knight and Scott were complaining about how they never watched The Hangover last time. "Hey hey guys calm your selves. How about this? We watch them all? Lydia's first because she's the girl and then Jackson, you can fight with Scott to see who goes next, alright?" All three heads nodded as Erica said "Thanks mom, I was two seconds away from killing them all." Stiles glared at her as he walked back into the kitchen. "Erica, no talking about killing your siblings" Stiles said in a mocking tone. Erica just snorted and cuddled back into Isaacs's side. He didn't realize until he was waiting for the popcorn to finish, that she had called him mom too.

The third time someone called him mom was Scott. Jumping through the window he said "Ma I really need some help with his chemistry homework!" Stiles turned around and looked at Scott through narrowed eyes "Why do you all keep calling me that?" "Calling you what?" "Mom!" Scott looked at him like he had three heads. "You mean you don't know?" He asked. Stiles dropped onto his bed. "Know what?" he asked. Scott was suddenly pacing and twisting his hands together. "Shit shit shit. You don't know! We thought you knew! I have to go Stiles, I'll call you later!" Stiles jumped up and called out but Scott was already out the window and running before he could ask what the fuck he was talking about.

It was 2 a.m when Stiles got a text that woke him from his sleep.

Scott; hey man. meet us downstairs we need to talk

Stiles; what do you mean we? Its 2 in the morning scott.

Scott; just open the door. We gotta talk.

Stiles; fine fine, im coming

Stiles made his way down the stairs, eyes half closed and as quietly as he could. He made it to the door and wrenched it open to find the whole pack on his door step, minus one sour wolf. He stepped back to let them in and they all filed in, only after stopping to give Stiles a hug or kiss on the way by. They walked into the living room where they pushed him onto the sofa where he proceeded to bounce his legs up and down. It was eerily quiet until he asked what he had been trying to figure out all night. "What don't I know?"

All six teens looked at each other trying to find the words but none said anything until Lydia groaned and said "Do you know why we call you mom?" Stiles just shrugged and answered "I thought it was because I made you guys food and stuff." They all laughed at that but said nothing. Finally Scott spoke up. "Stiles, there is a reason we call you mom. A very good reason in fact. Everything would be so much easier if you knew. Think hard Stiles. Think of the one very good reason why we would call you mom." Stiles sat on his couch wracking his brain for any possible reason. Going through all the research he had done over the past year he suddenly took in a sharp breath. "Mate. I'm his mate?!" The teens all looked at each other sheepishly. "Well fuck."
