Derek & OTA
It was getting easier for Derek to feel comfortable at events like this. He had been pretty new to town last Thanksgiving and had literally just reverted to his adult self after the curse Kate Argent put on him to turn him into a teenager, so this year was far better for that reason alone. The fact that things were going well with Elena and that he had his mother here made it even better.
People from Beacon Hills might be surprised to see Derek Hale at a party with a smile on his face, but he figured he had a lot to be thankful for and didn't see any reason to be unpleasant today.
