One possible scenario could be that Derek arrives just in time as Gerard is about to harm Stiles. Derek uses his werewolf strength and speed to fight Gerard off, perhaps with some cool combat moves. He then quickly gets Stiles to safety, like taking him back to the pack house.
Well, in the fanfiction, Derek might have been secretly following Stiles because he had a feeling Gerard was after him. When Gerard corners Stiles, Derek jumps into action. He could use his alpha powers to intimidate Gerard, making him back off. Derek would then carry Stiles away from the dangerous situation, and they might have a heart - to - heart conversation about what just happened on the way to safety.
In this fanfiction, it could be that Stiles was lured into a trap by Gerard. Derek, who has been keeping an eye on Stiles, detects the danger. He races to the scene. Derek might first try to reason with Gerard, but when that fails, he attacks. After a fierce struggle, Derek overpowers Gerard and rescues Stiles. Stiles is probably shaken up, and Derek stays by his side to comfort him, ensuring his safety and making sure Gerard doesn't come back for another attempt.
The main characters are Derek, Stiles, and Gerard. Derek is the savior. He's a werewolf with strength and abilities that he uses to protect Stiles. Stiles is the one in danger.

One scenario could be in the heat of an argument. They've been bottling up their feelings for so long that during a heated exchange, their emotions boil over and they end up kissing. It's a passionate and unexpected moment that changes the dynamic between them.
Another way is that Stiles might call in favors from other characters. He has friends like Scott and Lydia. They could all work together to create a distraction while Stiles sneaks in to rescue Erica and Boyd. Stiles is good at getting people to work together, and this would be a great strategy in this situation.
One possible reason could be a power struggle. Gerard might see Stiles as a threat to his own authority or plans within the story's context.
One interesting scenario could be that Stiles wears Derek's clothes to feel closer to him. Maybe Derek has gone away for a while, and Stiles misses him. Wearing his clothes gives Stiles a sense of comfort and connection.
Well, Stiles might become distrustful of Derek for a while. He could pull away from their friendship or alliance.

Stiles is a very loyal friend. He would see Erica and Boyd in trouble and feel compelled to help. In the show, he has always been there for his friends, and this would carry over into the fanfiction. He can't stand by while Gerard does something bad to them.
One possible plotline could be that it's a sign of comfort. Maybe Stiles is having a tough time, and Derek offers his jacket as a form of solace. Another could be a comical situation where Stiles accidentally puts on Derek's jacket thinking it's his own and Derek has a funny reaction.
