Lydia loves being in the pack Derek treats her like a beta and she can't help but love it. The pack is Scott,Stiles,Isaac,Erica,Boyd, and Peter. Jackson already left for London at this point. Derek is the alpha of the pack and they treat each other kinda like family. Lydia and Peter become good friends but when a bit of romance blossoms between them things change. Pydia and Sterek and scisaac plz enjoy.
