You hadn't told the team what happened to you while you were kidnapped. As far as you had told them, the unsub knocked you out and then you woke up to them rescuing you.

You hadn't told Spencer either. Though he knew the truth. The way your clothes were rumpled, your far off stare, the bruses that continue too far up your limbs, there was only one conclusion. That, and since coming back home to him, you've been uncharacteristically flighty.

He doesn't know what to do or how to help. He can't even prove what he suspects, cause you never said anything to the team, and the unsub isn't talking.
