The fantastic fourth series of Being Human comes to a close this Sunday night, and if you thought that the paranormal drama's 2012 run has been an emotional rollercoaster so far... trust us, you ain't seen nothing yet.

In powerful finale 'The War Child', Annie (Lenora Crichlow) faces the most difficult decision of her life (and death), while Tom (Michael Socha) makes a shocking decision and Hal (Damien Molony) is drawn deeper into darkness by the king of the Old Ones, Mr Snow (Mark Gatiss).

Being Human concludes Sunday at 9pm on BBC Three. In the US, the show airs on Saturdays at 9/8c on BBC America.
