'The Originals' Season 4 Spoilers: Klaus Threatens Marcel, Vincent's Fragile Truce As He Wages Own War Against The Hollow

"The Originals Season 4" is set to welcome a new villain summoned by The Hollow in the show's upcoming episode entitled "Bag of Cobras." This villain is expected to shatter what peace remains in New Orleans and threatens the home of the Mikaelsons and Klaus' daughter whom the family is striving to protect.

Based on the synopsis for "The Originals Season 4" Episode 6 entitled "Bag of Cobras", the Hollow will employ the help of a mysterious servant to do its bidding and it is up to Klaus and Elijah to identify the threat before it causes harm to their family and their city. Hayley, for her part, will ask for Freya's help to unravel events from her past, most especially those leading up to the death of her parents, TV Guide reported.

Speaking of Freya, actress Riley Voelkel, who plays the part said in an interview in TVLine that she is happy with the trajectory that her character. She said that recent developments in The Originals Season 4 saw her character developing a relationship with Keelin and this is a good thing for Freya who has never been close to anyone outside of her family. Keelin is the first character that Freya has bonded with that enabled her to show her emotional and vulnerable side.

Meanwhile, Vincent and Marcel's fragile alliance in "The Originals Season 4" may be out to the test by Klaus anew, according to BuddyTV. It can be recalled that Vincent, in an effort to save his people from Marcel, turned to sacrificial magic which unleashed a worse evil called The Hollow when he destroyed the Ancestral Plane where they used to rest.

While trying to stop The Hollow, Vincent is forced to work with Marcel to stop the evil from taking over the town but with Klaus and the Mikaelsons making their own move against The Hollow to protect Hope, it seems that Vincent and Marcel's partnership may not be for long.  The Originals Season 4 Episode 6 returns to The CW on April 28.
