Fallen - Season 1 Episode 4 Outcast

Howson organises the capture of the creature that attacked Luce in the lake and interrogates it-establishing it is an Outcast, an ancient creature with a hive mind. Luce comforts Daniel over his grief for his friend, Cassie while they await the return of the decrypted medical files. Learning that the files will be returned during an evening activity, Luce tries to work out how to sneak away to collect them. Salvation comes when Penn's father turns up at the facility, looking for answers about his 'dead' daughter. Luce and Daniel retrieve their files, but the content turns their world upside down.
