I do understand the importance of a backstory and how we need certain details to connect the dots.
But give us at least a little action, c’mon!
Thank goodness Isaiah Mustafa spent the entire hour with his impressive bare torso bandaged.

Otherwise, I might have been bored.
Luke questions, The key to saving you?
The key to stopping Valentine.
Magnus explains that Luke is experiencing a side effect of the poison from the Alpha wolf bite.
He needs ingredients for a super fancy antidote, and he needs them NOW.
Jace and Simon argue over who gets to go downworld pharmacy shopping on Clarys behalf.
Jace knows a guy.
Magnus also asks them to call Alec because he needs virgin shadowhunter energy.
Jace makes the call, even though he is still ticked at Alec for his dangerous escapade with Clary.
Simon scurries after him so he can be Clarys knight in shining armor, too.
He pokes fun at Jaces relationship with Alec, and Jace pulls the parabatai bro card.
Simon bets Jace that Alec wont show up.
He claims Jace treats Alec like a lap dog.
But Jace laughs, telling Simon he acts the exact same way around Clary.
Thats when Simon loses it and shoves Jace against a brick wall holding a knife to his throat.
In one motion, Simon is on the ground as Jace hovers above him, peppering questions.
What happened at the vampire hotel?
What is going on?
Where did you get the frames for your hip glasses?
Okay, maybe he didnt ask that last one, but Jace knows something is not right with Simon.
Back at the Institute, Mama Lightwood struts around with a permanent frown on her face.
Her husband, Robert, is back in town with Max (the youngest Lightwood) in tow.
Robert is pretty upset that Clary is MIA and demands that Izzy and Alec retrieve her immediately.
Alec suspects something is going on with his parents when he finds his mom crying.
Apparently the Lightwoods need to adapt and present a united front.
Izzy makes Alec promise not to marry for political alliance.
They will restore the family name on their own.
Shes not going to placate the seelies, either.
But she is going to start dressing less hoochie and more like her mother severe ponytail included.
A frustrated Alec storms out of the training room for a quick shower and to musk up.
Hes going to see a warlock about a werewolf.
NEXT: A walk down Valentine Memory Lane
Magnus needs Alec to hurry up.
His blue magic is working, but the poison in Lukes system is spreading.
Magnus encourages Clary to draw out her feelings to see if she can remember anything about the Mortal Cup.
I guess he didnt have any adult coloring books to help ease her stress.
Clary sketches as Magnus gives her a history lesson in Daddy 101.
Young Valentine thought downwolders should be killed, even though they are only half demons.
This became an obsession, and he developed some severe anger issues.
He wanted to create a new shadowhunter army, and he needed the Mortal Cup to do it.
Luke and Jocelyn fought valiantly.
She was able to grab the cup and disappear.
Suddenly, Luke starts to have a seizure.
Alec swoops in to help.
Magnus asks if he can siphon his energy?
Alec gives him a sultry look and says, Take all you need.
Jace and Simon arrive with the last ingredient for the potion.
They only had to fight one demon to get it.
Magnus and Alec channel each other as Clary pours the potion down Lukes throat.
I cant really blame him.
Have you seen those arms?
Magnus later admits to Alec that he has unlocked something in him.
Someones got a crush!
Clary thanks Alec for helping out.
She mentions that shes glad he and Jace are back on good terms.
Alec actually grins and says, I didnt do this for Jace.
Did Alec just come out of the closet?
Jace comes in to give Alec a parabatai bro hug.
Then he intimately touches Clarys face and hair just as Simon walks through the door.
Magnus sets Luke up in his pimped out bed with a thousand pillows.
Clary begs him for the rest of the story.
She has to have ALL the information to unlock her moms annoying riddles.
What is he not telling her?
The reason Valentine went crazy is because he and Jocelyn betrayed him.
They fell in love.
And Val got angry.
Valentine became obsessed with winning her back.
He wanted to be the best soldier for her and even experimented with drinking downworlder blood.
Once he crossed that line, he was gone.
He became fixated on finding the Mortal Cup and creating more shadowhunters.
This is, of course, forbidden.
He locked Luke in a warehouse where he was attacked by werewolves.
Valentine was surprised to see Luke the day he stole the Mortal Cup.
He assumed he would have killed himself for being an abomination.
Thats when she grabbed the cup and ran, with Valentine close on her heels.
Luke assumed she was dead because Valentine was that bad.
It turns out, Jocelyn is a fighter.
Clary still has no clue where her mother would have hidden the cup.
She digs around in her bag and pulls out the mysterious box with JC engraved on the side.
Luke looks like hes about to hurl.
He swallows and calmly tells Clary that JC stands for Jonathan Christopher her brother.
He died in a fire.
A fire that Valentine started.
Clary slams her hand down on the box, and it magically becomes a drawing on her sketch pad.
Luke is mesmerized by the fact that she clearly has angelic powers.
Now, who wants to take bets on how long it will take them to find it?
