Things are about to get extra steamy when Reign returns after Kenna offers Penelope some tips on how to keep the king "entertained."

Mary & Francis' Marriage 'At Stake?'

In a clip of the next episode, called No Exit, Penelope is seen looking over a dress when she tells a seamstress that it needs more red and lace to keep the king wandering to "sad old habits." This is likely a reference to Kenna, who happened to walk in.

As the seamstress leaves, Penelope wonders if Kenna came in to get the ring she has on her finger.

Mary's Character To Change That Will 'Cost Lives?'

"Not at all, you can keep it," Kenna responds. "I actually came here to help." Penelope hesitates to believe that when Kenna asks her if she's noticed that the queen has made no effort to remove her.

"She tried and she failed," Penelope says.

Kenna then reminds Penelope that Queen Catherine knows what she's doing when it comes to "poisons," and if she wanted to kill Penelope, then she would've done it. Apparently, Penelope is alive to keep the king distracted. This leads into a discussion on Kenna not wanting King Henry back, and some advice that Penelope should consider if she wants to keep his interests alive, which are kinky tips.

"Have you tried blindfolds?" Kenna asks Penelope. "Having him listen to the sound of your voice?"

Kenna also offers hot wax on his chest, which doesn't seem to interest the king's current flame. But when the "standing cross" gets brought up, that's when it appears that things will really entice.

Reign airs on Thursdays at 9 p.m. ET on The CW.
