Morning Song – Jewel
He had taken more time than he had planned to get to the scene, but it was all Jess' fault. Not that he could tell that to Mac.
After agreeing with him that he had to go to the scene, she still had refused to give him the keys to the handcuffs, and started making things that made it pretty difficult for him to concentrate enough to open the lock. And of course that he had to change afterwards.
So when he arrived to the scene 20 minutes later than he should have, he couldn't just go ahead and tell Mac that Jess had handcuffed him to the bed, so he lied. "Sorry Mac, the traffic was crazy out there!"
And Mac just gave him an amused look, not buying his act at all.
