We’re still two months away from the debut of Doctor Who’s eighth season, but a new teaser gives us a peek inside Peter Capaldi’s version (literally) and hints at the return of an old enemy.

The all-too-brief teaser shows Capaldi’s Doctor getting electrocuted in the TARDIS, and we glimpse the two beating hearts that keep the Time Lord kicking. There’s also a very creepy voice chatting over the visuals, saying, “I see into your soul, Doctor. I see beauty, divinity, hatred.”

It sounds very Dalek-y, and some fans are speculating it's the voice of Davros, the Doctor’s archenemy, who created the Daleks. It makes sense, and it’d be a nice throwback baddie to give Capaldi’s Doc a run for his money during his first full season.

Check out the teaser above and let us know what you think.

The new season of Doctor Who debuts Saturday, Aug. 23.
