Unsure of where the treasure is hidden, they attempt to get into the mindset of the knights.
Nick comes up with a brilliant idea: Turn the lights off.
So, what if the knights had left a clue that could only be discovered in pure darkness?

Speaking of Portland, the manhunt is on for Marwan, who shot mayoral candidate Andrew Dixon.
Uh oh, trouble in secret lover paradise.
Renard and Hadrians Wall have two different plans for taking care of Marwan.
HW wants to use him.
On the streets of Portland, Eve uses her powers to have a bicyclist knock Marwan over.
She uses this as an opportunity to swipe his phone.
Utilizing her Hexenbiest powers, she renders Manwar unconscious while HW bugs his phone.
This could lead them to key contacts inside of Black Claw.
Renard has other plans, though, and he completely ruins everything.
Renard, Wu, and Hank go after Marwan.
It leads to an altercation between a woged out Renard and Marwan… which then leads to Marwans death.
Meisner confronts Renard and is understandably pissed.
These two are so sweet.
As if things couldnt get any more awkward, in walks Lucien.
In fact, Renard thinks his face lookssogreat on it that he doesnt immediately shoot them down.
In his defense, it is a really nice poster.
They have bigger problems to deal with, though, because Rosalees creepy stalker, Tony, shows up.
He demands $5,000 from Rosalee and then starts smashing everything in the shop!
This isnt the craziest part of the altercation, though.
Oh, yes Adalind did that with her mind.
It freaks Tony out enough that he flees.
And it freaks Rosalee and Adalind out, too.
This is not going to end well.
When Monroe and Nick get back in town, everyone meets at the Spice Shop.
After opening the chest (which required Nicks blood), they pull out something wrapped in cloth.
Nick delicately unwraps it to reveal … a stick!
It looks like just a piece of wood, but these guys should know better by now.
All of a sudden Monroe starts to collapse from his wound, and it appears he has blood poisoning.
Nick realizes that its because of the magical stick.
What exactly is this thing anyway?
Im going with Bellatrixs wand or a dragon toenail, but I could be wrong.
How long will it be before Black Claw tries to snatch the mystical stick?
Otherwise, they would be using it themselves, not trying to prevent it from being found.
Whatever it is, it will probably be a major factor in this war against Black Claw.
