As if time traveling weren’t confusing enough, now we’re adding angels into the mix?

Well, not exactly. “Supernatural’s” Curtis Armstrong, who played the villainous angel, Metatron, will be paying Raimy (Peyton List) and Frank (Riley Smith) Sullivan a visit on Wednesday’s (Nov. 9) new episode of “Frequency.”

Armstrong will play Karl, a trickster-type quantum physics professor, who is in jail for murder in the 2016 timeline. He’s not the kind of person you’d expect Raimy to be hanging out with, but when he requests a visit from her, claiming he’s got important information, Raimy has no choice but to play along.

“He’s so good,” List says of Armstrong. “I remember we had one day where he had a lot to say and it was kind of a treat for me because I just got to sit back and watch him. He made so many brilliant and so many interesting choices and I just felt kind of spoiled. It was a really fun day of work actually. Maybe not as fun for him, he had to talk a lot, but it was really, really cool.”

We already know Armstrong is more than capable of playing cunning and malevolent, thanks to his time on “Supernatural” — but whatever tricks he’s trying to play, we’re keeping our fingers crossed he doesn’t have anything too terrible planned for Raimy.

Being a quantum physics professor, we can’t help but wonder if Karl will finally shed some light on what allows Raimy and Frank to communicate through time-traveling radio waves. And if this guy has solved the mystery of speaking to the past and future, what the heck is he doing in jail?

“Frequency” airs Wednesdays at 9 p.m. ET/PT on The CW.
