After Thomas had his face bitten off by Pip, Gregory and Estella made their way back to Craig's house so Thomas could regenerate. Whilst Gregory and Estella waited, Estella was trying to close the portal to hell while Gregory decided to mess around on Craig's computer. Specifically his Tumblr blog..

[Gregory] "It’s… almost as if Craig wants to lead us right to him…" He moved the PC mouse.

[Estella] "Yes, I’m 'sure' he left his computer on exactly for this revelation of yours."
