"Doctor Who" closes out its seventh modern season Saturday with the season's best episode, "The Name of the Doctor."

Written by showrunner Steven Moffat, the episode does exactly what he said it would: It solves the puzzle that is Clara (Jenna-Louise Coleman) and pushes forward the mythology of the Time Lord. Get ready for major surprises, Whovians.

"The Doctor is moving forward as he always does and he wants to solve the mystery of Clara," Moffat told writers during a conference call earlier this year. "He's not thinking about all his previous incarnations and his previous adventures; he's thinking about the future.

"That for me is important. The show must never feel old; it must always feel brand new."

Moffat was answering a question about the upcoming 50th anniversary episode, but it feels apropo to "The Name of the Doctor," which debuts at 7 p.m. CT May 18 on BBC America.

Moffat and director Saul Metzstein give more than a glancing nod to classic "Doctor Who" while masterfully finishing the season in which The Doctor (Matt Smith) has struggled to understand "The Impossible Girl"--his latest companion, Clara. It's boggled my mind, to be honest, and I haven't even watched the final scene that the BBC held back from the screener.

In the episode, Clara is summoned to a conference call with the Doctor's Victorian-era pals Madame Vastra (Neve McIntosh), Jenny Flint (Catrin Stewart) and Sontaran commander Strax (Dan Starkey). Another old friend joins the group, too, but spoilers! (Yes, that is a clue.)

Just as the group sits down to tea, though, the deadly Whisper Men appear and what happens next leads the Doctor to the one place in all of time and space that he should never go.

The Whisper Men are sure to become a fan favorite monster, as they already have for Coleman, who wasn’t able to reveal a lot about them when we spoke earlier this year.

"I can tell you they have have a style. There's something in their style that is just pretty creepy," she said, laughing. “That tells you nothing, does it?"

Coleman and Smith elaborate a little more on the new villians in the second video below. The first is a preview to the episode.

I fear if I go on more I’ll really spoil something. But suffice to say, you’re going to love learning the truth about The Girl Twice Dead, The Impossible Girl, The Only Mystery Worth Solving—Clara, that is.

As Coleman said, all those Claras we’ve met come together in unexpected ways, and it’s so cool.
