The Librarians... and the Rule of Three

Because high school.

It's back to school for the intrepid Librarians this week, as the book of cuttings leads them to a STEM fair in Chicago, where the nerds fight with science for prestigious scholarships. Unfortunately, this particular science fair is dogged with bad magic, which is causing various contestants to fall prey to 'accidents'. All eyes are on top prospect Amy (or her super-competitive mother,) but the true culprit may be someone just a little older and much more dangerous.

Cassandra and Stone get to shine this episode. Cassandra is in her element as the former nerd-queen, while Stone knows what it's like to wear a mask to try to fit in, allowing him to bond with the early red herring outsiders. After a couple of weeks of Ezekiel Jones hail Mary's, Stone and Cassandra also get to make the save this week, with a dazzling science/magic theory and architectural surveying combo. Ezekiel has a few moments, but is basically lost in this world, not least when faced with a science fair contestant determined to prove that sea otters are the most evil and dangerous creatures on the planet.

The eventual solution to the mystery is kind of awesome; the big bad has created a smartphone 'brain gym' app which actually allows the use to cast a spell to create an advantageous situation by messing with your rivals. This has allowed people to unknowingly bring misfortune on others, with the ultimate goal of harvesting the magic from the eventual threefold backlash (a solid and fairly accurate invocation of the titular rule of three) from using magic to do harm. 

And who is our big bad? 

"Does my ambition look big in this?"

It's Morgana la Fey, a sassy, snarky red-head with awesome magical power and a take no bullshit attitude.

Jenkins: This is Morgana la Fey.

Blair: I know that name.

Morgana: You're a Librarian?

Blair: Where do I know that name from?

Morgana: Oh. Guardian.

This also gives us another piece of the puzzle in the larger 'war', as she refers to Jenkins as Galeas (the old name for Galahad - although I initially misheard it as Peleas the Fisher King - which would tend to make him Dulaque's son.)

The Librarians... and the Rule of Three is another fun episode, with a slightly dark edge. It's not as good as ...and the Fables of Doom, but it's still pretty good.
