The Evil Queen (Lana Parilla) is again one step ahead of the heroes come the next episode of "Once Upon A Time" season 6, "I'll Be Your Mirror."
In this installment, Emma (Jennifer Morrison) and Regina (Parilla) plot to lock away the Evil Queen in a prison "of their own making," as the synopsis teases.
This prison is revealed in the promo for "Once Upon A Time" season 6 episode 8 to be the world that lies beyond a mirror. The duo successfully devises one but trapping their adversary there is another story.
"Everything you can dream up, I've already dreamed it," the Evil Queen told a shocked Emma and Regina, who she, in turn, traps in the mirror.
There, they are welcomed with a not-so-friendly dragon who the Evil Queen hopes would eat the two alive, but that is not the only thing the sinister royalty has planned for the heroes in "Once Upon A Time" season 6, episode 8.
The Evil Queen will also impersonate Regina to talk to Henry (Jared S. Gilmore), who is preparing for the school dance and has never been more nervous to impress Violet (Olivia Steele-Falconer).
Acting as Regina, the Evil Queen gives Henry a piece of advice that the synopsis for the episode warns could lead him down a sinister path and one that will "darken his heart."
The Evil Queen is also seen standing behind an almost unseen Henry in the upcoming episode's promo, instructing someone to "kill them," which appears to be in reference to Emma and Regina.
As all this happens in "Once Upon A Time" season 6 episode 8, Snow (Ginnifer Goodwin) and David (Josh Dallas) adjust to their new life, which is the doing of the Evil Queen herself.
In addition, Zelena (Rebecca Mader) will make herself busy by helping Belle (Emilie de Ravin) to protect her unborn child from Mr. Gold (Robert Carlyle) with a magical object, which they intend to steal with the help of Aladdin (Deniz Akdeniz).
"Once Upon A Time" season 6 episode 8, "I'll Be Your Mirror," airs on Sunday, Nov. 13, at 8 p.m. ET on ABC.
