Something Derek had told his three Betas early on was that the larger the pack, the stronger each individual wolf -in particular, Derek- were. What he hadn't mentioned was how finding your mate, your actual soul mate, not only did that, but helped the wolf remain calm, relaxed.

In the time since he and Stiles had embraced this, Isaac had already started learning to control his wolf on a full moon, and when in Stiles' presence, was even able to change back.

Which was why, despite it being the night before the full moon, Isaac was able to relax by his mate's side, nose tucked under his chin. "Love you too."
