Stiles didn't know 100% what was on the tape but out of the two days he had been with Eterna, Stiles confessing he wanted to stay with Derek and he wanted the werewolf were the only major things that happened. It wasn't hard to guess that Eterna would give it to Derek.
"Yes, sir. I will be waiting," Stiles said after he got out of the car. He left with the guard, following him, back to his cabin which looked like had been cleaned since Stiles last was there.
Stiles didn't waste any time stripping and getting into the shower. He didn't want to smell like Eterna any longer than Derek wanted him to.
