Sam Witwer and Mark Pellegrino Sam Witwer and Mark Pellegrino

What could be sweeter than a father and child reunion? Well, if Dad is Being Human's brutal bloodsucker Bishop (Mark Pellegrino) then, basically anything! Bishop may have been decapitated last season by Aidan (Sam Witwer), the vampire he sired centuries ago, but dead or not, on Feb. 20 he's back. The onetime Boston vampire capo returns to Syfy's addictive supernatural show as a hallucination to haunt the troubled Aidan. He's also seen in flashbacks, including during World War I, as pictured above.

In an episode all about family bonds, Bishop is quite happy to offer paternal advice as Aidan must deal with the unexpected and unwelcome appearance of his own rebellious "son" Henry (Kyle Schmid), who decades earlier had betrayed his maker by bedding the vampire princess Suren (Dichen Lachman). We'll have to wait to find out whether father knows best. One thing we are certain of, no one plays a devious bogeymen — Lost's Jacob and Supernatural's Lucifer come to mind — than the hard-working Pellegrino. It might be cruel, but we hope Aidan can't get Bishop out of his mind.

Being Human airs Mondays at 9/8c on Syfy.
