At lacrosse practice

It was 4pm on a warm Saturday afternoon and the whole team had already started doing drills when Stiles and Scott came running onto the field, dragging their equipment behind them. Isaac nudged Boyd and they both laughed at the angry look on Coach Finstock's face.

"McCall, Stilinski what in God's name are you two doing? You're late."

Scott shrugged while Stiles began an over-exaggerated story to explain why they were not on time, but Coach just shook his head and muttered something about never winning a championship game and pointed toward the other players. "Just get on the field and stop wasting my time."

The two best friends nodded simultaneously and rushed into the next drill. Sadly they winded up standing behind a very pissed off Jackson while waiting their turn.

"I can't believe that Coach just let your stupid friend on the team," said Jackson. Scott raised his eyebrows and laughed. "What are you complaining about now dude?" asked Stiles.

Jackson frowned at him and pointed to the front of the line. "Oh you mean Boyd?" asked Scott. "Yeah, just because he did alright in one game, that he wasn't even supposed to be in might I add, coach just let him on first string," said Jackson angrily. "He even bumped up Isaac too."

"Oh come on!" complained Stiles. "He moved up that mini psycho and not me? This is some serious BS. Can you believe this Scott...Scott?"

Stiles turned around and saw that everybody in front of him had already gone and that he was just standing there talking to himself. Well almost everyone had gone.

"I heard what you said Stilinski," said Isaac. Stiles looked up and saw the blue eyed teen reclining against the net with and evil grin on his face. Isaac picked up his stick and began making his way over to Stiles.

"Oh, hey Isaac, h-how are those wounds doing? Are they healing up nicely?" Isaac grinned at Stiles and nodded slowly. "Yep, they feel fine. You know I wanted to thank you for coming to check up on me today."

Stiles smiled nervously at the beta, "Yeah, well it was no big deal I was just-hey what the hell do you think you're doing?" Isaac snatched Stiles lacrosse stick from his hands and began glancing over the fine material. "I need a new stick, mine is busted up."

Stiles gave him an annoyed look and tried to get his stick back. "You know Isaac I've tried to be nice with you, but I will kick your ass to the next full moon if you don't give it back."

Isaac glared at Stiles and cracked the lacrosse stick over his knee and threw it off into the general direction of the other players who had already started to watch the two teens argue. "What the hell dude? You broke my stick!" yelled Stiles "So what?" said Isaac

"So? You broke my effing stick and you're going to pay for it. That cost my dad like hundred bucks."

Isaac rolled his eyes and looked around at all of their teammates who had surrounded them and then at their coach, who was also eyeing him accusingly. All of a sudden it dawned on him. This is what Derek meant…

And as if on cue Derek appeared on the field, his eyes burning a hole into Isaac's skull as he drew closer and closer to the group. Isaac could just picture his wounds from earlier re-opening and it made him feel sick.

"Who the hell are you," asked Coach Finstock as he and the rest of the team watched the Alpha approach them. Derek ignored the coach and went straight for Isaac. He grabbed him by the back of his shirt collar and pulled him away from the team. "I need to have a word with one of your players."

Stiles grinned and started to laugh, "Ha, now you're in trouble!" Scott shook his head and began walking away from the crowd.

"Oww, Derek let go," cried Isaac as he felt the Alpha's claws dig into the back of his neck. Derek growled and pushed him into a fence. "Seriously Isaac, you told me that you weren't going to act without thinking anymore and literally it's only been a half an hour since we've had that discussion. What do I have to do to make you listen?"

Isaac shrugged while doing his best to avoid eye contact with his Alpha. Derek sighed tiredly and stepped a little closer to him. "Look, I get that it's difficult being a new wolf and trying to control yourself when you're angry is next to impossible sometimes, but you need to realize that your actions have consequences."

"I know Derek, I think understand now. When I saw everyone's eyes on me after I broke Stile's stick I felt kind of ashamed of myself…but I mean he did call me a psycho." Derek shook his head, "No, I don't think you fully understand me yet Isaac. You're too impulsive and we really need to fix that. You don't see Erica or Boyd going around breaking things all the time do you? I believe that I've been too lenient, so tomorrow I've got a special exercise planned for you."

Isaac glanced up from the ground and cocked his head to the side. "What kind of exercise?" Derek grinned devilishly, "It's a surprise, be here on this field at 5am tomorrow and tell Stiles to come and bring his lacrosse pads with him."

"Wait, why does Stilinski have to come?" asked Isaac. "Because," said Derek. "I said so; now get back to practice before they kick you off the team." Isaac paused momentarily then ran as fast as he cold back to the field without turning back to see whether or not Derek was still there. "What am I going to do with that kid?" he said to himself.

Then, seemingly out of nowhere Erica appeared and rested her arm on Derek's shoulder. "Don't worry; I think you're finally starting to get to him. Plus I can't wait to see what you're going to use Stiles for tomorrow. You're not going to have Isaac hurt him are you?"

Derek smirked at the blonde, "No, no that would completely defeat the purpose of the exercise, but if Stiles does happen to get hurt that wouldn't exactly be a bad thing." The two wolves began to laugh when all of a sudden Derek stopped and looked at Erica. "What's wrong?" she asked.

Derek glanced across the field until his eyes landed on Isaac, who was at the moment comically trying to put Stiles stick back together with no success while their coach stood beside him shouting out nearly every curse word known to man.

"I need you to stay here and watch the rest of this practice and report back to me if he does anything else that could get him in trouble." Erica complied and strutted off to go sit on the bleachers.

As practice continued Isaac would occasionally eye the sidelines to see if Erica was still there and every time he looked over she would smile and wave. "Hey Isaac, looks like you've got a fan," said Danny.

"Woo-hoo, Go Isaac!" cheered Erica from the stands. He knew that she was only watching him because of Derek, but she was becoming a bit of a distraction. "Don't remind me," he said while passing the ball to Boyd who was also grinning at him because of her. "Man tomorrows gonna suck."
