Lacey Turner, fresh from Eastenders, joins Being Human for the first episode of the new series. She plays Lia, who Mitchell (Aidan Turner) meets in purgatory, which he enters to rescue Annie (Lenora Crichlow) who is trapped there waiting to know her fate.
Leaving the memories of their much-loved house in Bristol behind, George, Nina and Mitchell have settled into their new home in Barry, South Wales – a kitsch B&B named Honolulu Heights that boasts many benefits for supernatural sharers; a large basement providing a safe and sheltered environment on a full moon, for one.
Craig Roberts, who starred in CBBC's Young Dracula (and will soon be seen as the lead in feature Submarine), plays a vampire Adam who crops up in the main series of Being Human and then his tale spins off into the new web show, Becoming Human.
Being Human returns to BBC3 at 9pm on Sunday 23rd January.
