Crowley watched the recording as he chanted his spell. It was amazing how quickly magic worked once you got everything right. With any luck, the Winchesters would be so caught up in their work that they wouldn't notice his tricks for weeks. Maybe even months! By then, that damned angel would be ready to strip his wings off for Dean, and he guessed that Dean would gladly go to hell again to save Castiel. All he really needed were a few more days of 'magic moments' to seal the deal. Maybe next time he'd get them started right before the moose got home. That would be a good time.
It was lucky of him to have found the Angel tablet, or none of this would have worked. Humans were always falling for witchcraft but angels were tricky. Most human tricks didn't work on them. That's where the Angel tablet came into play. There were certain spells and ingredients that angels were weak to, and the right combination of those items plus the right words in a spell meant that Crowley could basically now control when and where Castiel got a woody. And with the hex bag carefully hidden in it's spot, he could control Dean all day.
Crowley's let out an evil giggle as he watched the two lovers handle their feelings for each other. "Never enough time, is there Dean? Don't worry, I'll make sure you're well snogged tonight. And you too, Cas old friend. You're going to know what it feels like to have Dean up your arse for once." The King of Hell watched the camera feed as the hunters and their friends climbed into the Impala and drove away. Unfortunately, he'd only managed to rig the motel with cameras and hex bags. It meant he wouldn't be able to influence anything Dean and Castiel did while away from the motel, but he had a feeling he wouldn't need to. If he played his cards right, the daft lovers would keep up the romance even without his desire-boosting spells.
"Alright who's next? Ah, Liza, you're up. You know what to do. Make me proud," Crowley ordered.
A twenty-something redhead stepped forward and blinked her eyes, showing her demonic nature. "It will be done," she replied. She gave a slight bow as she left the room and headed for the parking lot of the building.
