Ever since you'd joined the BAU, there had been a tension between you and Hotch. His eyes lingered on you with an almost sadness that you couldn't quite place, and more often than not, he seemed to be forcing a greater professional distance than was nessecary. He was never cold or unkind, just... distant.

you weren't even the only one who noticed. You'd asked Morgan about it one day, and he'd told you about the Agent who's spot you filled in.

Persephone Hotchner had been a member of the tight knit group, as well as being Hotch's daughter. She had brutally died at the hands of an unsub eight months before your arrival.

There was a resemblance in your appearances, and Morgan had chalked up Hotch's behavior to you reminding him of Persephone, and you'd accepted it, choosing to ignore it.

you should have listened to your gut. You'd worked late to finish your report, and it was just you and Hotch left in the bullpen. One minute, he was offering you a ride home, insisting that it was too late to take a bus. The next...

The next, you're waking up in an unfamiliar apartment. An apartment which, unknown to you, was built underground as a replica of Persephone's.
