Stiles knew Derek was going to leave. That was the only reason they’d slept together, that Stiles had let himself go for one night. It had been strangely emotional, way more intense than he’d expected. Stiles woke up feeling vulnerable, but that was fine, because they never needed to see each other again.
That’s why, months later, when he sees Derek across that road through the forest, he doesn’t know what to think, much less what to feel.
Except for totally freaked out.
