A new behind-the-scenes still featuring Thomas Gibson, who portrays Hotch in Criminal Minds, and producer and writer Virgil Williams from the filming of episode 16 was recently revealed.

The image was tweeted by the official set_report account for the show, with the following caption:

It seems likely that Gibson might be directing this episode too, as he has worn that hat in this season before. The tweet seems to suggest that, probably showing the writer-director team arm in arm.
