In subsequent intercuts, George is seen finding a suitable place in the centre of the woods, stripping naked, and then slowly and painfully transforming into a werewolf, screaming throughout the process.
Mitchell reaches the end of his musing — his eyes turn jet black, his fangs lengthen and he attacks Lauren, drinking her blood.
Several character traits were set up which would carry over into future episodes including George's stern discipline and denial regarding his werewolf condition (as well as his own vulnerability to its broader effects) and Mitchell's balancing act between a vampiric sense of superiority, his self-disgust at his own murderous past and his tendencies toward temptation.
He originally conceived Being Human as a non-fantasy drama about three flatmates struggling to cope with various inconvenient conditions (addiction, long-term illness and psychological problems) before realising that it would be more entertaining if adapted to a fantasy setting.
Having written the Doctor Who episode School Reunion for the programme's second series (broadcast in 2006 but filmed the previous year) Whithouse was contacted by the BBC and invited to submit a pilot script for a TV show, as part of a set of pilot episodes to be made and broadcast on BBC3 with the option of possible future commissioning.
