It seems like forever since fans of ‘Warehouse 13’ last saw Artie, Pete, Myka, Steve and Claudia. If you recall, during the mid-season finale back in October, something deadly was let loose into the world. We’ve waited 6 months to find out what happens next, and if you’re like me, waiting even a moment longer is too long to wait. Luckily, thanks to Syfy, fans won’t have to wait until the end of April to watch the premiere of the second half of Season 4, as we have it here for you to watch right now!

‘The Living and the Dead,’ picks up where we last left the Warehouse team as they rush to prevent a pandemic from taking hold and causing immense casualties in the human race. The episode boasts a pretty good list of celebrity guest stars with the return of Lindsay Wagner as Dr. Vanessa Calder, Kate Mulgrew as Jane Lattimer and Roger Rees as James MacPherson. Joining them will be Polly Walker (‘John Carter,’ ‘Caprica’) and James Marsters (‘Angel,’ ‘Buffy the Vampire Slayer’).

Speaking of ‘Buffy,’ Marsters won’t be the only ‘Buffy’ alumni to appear in the series. Expect to see Anthony Head, who played the slayer’s Watcher, to join the cast as the villainous Paracelsus. His character will play a major role in the last 3 episodes of the season.

Other celebrities set to appear in the second half are Joel Grey (Doc from ‘Buffy the Vampire Slayer’), Steve Valentine (‘Crossing Jordan’), Missi Pyle (‘Galaxy Quest’, ‘Charlie and the Chocolate Factory’), and Enrico Colantoni (‘Galaxy Quest’, ‘Contagion’). And if you miss seeing H.G. Wells around the Warehouse, fear not! Although Jamie Murray is now starring in another Syfy network show, ‘Defiance,’ she did make time to film an episode for this season’s second half.

There are 10 episodes to go before the end of Season 4, and it all starts with the one below! Sit back and watch ‘The Living and the Dead’ (with no commercial interruptions!) then let us know what you thought of the episode!

‘Warehouse 13’ returns to Syfy beginning Monday, April 29th at its new time, 10pm.
