Reign
Will King Henry survive Season 1 of "Reign"? Sven Frenzel/The CW

The insane King Henry will continue his rule into episode 18 of “Reign” … and unfortunately for the castle crew that means everyone should be worried.

As we previously reported, the king’s failing mental state will be front and center in the episode 18, “No Exit.” As he continues his “downward spiral,” King Henry will make a surprising move – putting Penelope in charge. Who is Penelope, you may ask? She’s the kitchen help who a couple weeks ago won the chance to be “Queen For The Day.” But as “Reign” viewers can see, that “Queen For The Day” became extended when she began hooking up with King Henry.

With the country at stake, Catherine and Kenna will be putting their differences aside and coming together to take “drastic measures” in securing the safety of the castle. And “Reign” fans can see a sneak peek look of what Kenna and the queen have up their sleeves in a newly released video clip:

The sneak peek clip shows Penelope discussing a new dress with the castle seamstress. “It needs more,” she tells the woman. “More red, more lace.” And when she sees Kenna walk in, Penelope adds that she needs to “keep the king’s eyes from wandering to sad, old habits.

Penelope initially believes that Kenna’s paying her a visit to retrieve a “miserable, little ring” she’s wearing. However Kenna surprises her by saying she came to help.

“You notice that the Queen makes no effort to have you removed?” Kenna questions Penelope. And when Penelope explains that she tried and failed, Kenna reminds her that Catherine is an artist with poisons.

“You’re alive because you serve a purpose,” Kenna tells the young girl. “To keep our poor, mad king distracted.”

Penelope agrees that he’s unwell and that she’s trying to divert him from his pain. However Kenna sassily tells her that she has obviously lost her charm in diverting the king if he’s returning to “sad, old habits.” Convincing Penelope that she doesn’t want Henry back, Kenna offers some advice to “keep the king’s interest and survive by his side” … and Penelope eagerly laps at it.

Although unimpressed by Kenna’s suggestions of blindfolds and hot wax, Penelope becomes intrigued by Kenna’s last suggestion -- “the standing cross.”

While it’s unclear what “the standing cross” is, we have a feeling that it’s something a little more than something kinky for Penelope and King Henry to try in the bedroom. If Kenna has teamed up with Queen Catherine, it’s likely that the pair is setting Penelope up.

“No Exit” will air on The CW on April 17 at 9 p.m. EDT. What do you think will happen in episode 18 of “Reign”? Tweet your thoughts and theories to @AmandaTVScoop.
