Clary has a nightmare about a mysterious man named Magnus stealing her memories.
The dream turns out to be not so horrific when she wakes up to Jace comforting her!
Its too bad Clary was still halfway comatose because Jaces face morphs into Simons face.

I guess the BFF will have to do for now.
Guess who else has a smoking hot bod?
Jace explains that Magnus Bane is the High Warlock of Brooklyn.
Speaking of restless, Simon is fed up with hanging around the Institute as a glorified prisoner.
Clary begs him to stay.
Theres no way they can go back to their old lives.
Everyone they know is in danger, and its best if Simon sticks around.
He doesnt need Captain America to protect him.
Jace laughs, claiming hes not going to keep saving Simons life.
Be gone, mundane!
Clary wants to stay with her people.
Her fellow shadowhunter people.
Simon reads the message loud and clear.
Theres no time for sad good-byes.
Hodge comes in to share a little intel on Magnus.
Hes 300-years-old, and he loves a good party.
Theres only one way he will come out of hiding, and thats to attend a downworlder rave.
Hodge gives the kids a ruby necklace that once belonged to Magnus as extra leverage.
Get to Magnus before Valentine.
That means the exact same outfit for the guys and slinkier, shorter outfits for the girls.
I have no idea where they are going to hide their seraph blades.
Simons mom wants him to be more responsible.
Maureen wants to know if hes hooking up with Clary?
Oh, sweet girl.
Simon is the Mayor of Clarys Friend Zone.
She accidentally knocks over a picture frame and cuts her finger.
Simon is spellbound by the blood.
Maureen receives this bizarre behavior as rejection.
Simon swipes his finger through the blood on the glass and tastes it.
I cant wait to see him sparkle in the sun!
Wait wrong book series.
NEXT: You call that a demon?
Before Clary can answer, Alec shoots down a Circle Member with his bow and arrow.
Magnus takes a moment to be impressed before jumping into the portal.
With no memories retrieved and the ruby necklace gone, Alec is one unhappy camper.
Clary snaps at Alec for being a total jack wagon.
Hes not strong enough.
He enlists Alecs parabatai bond to double their efforts.
The boys stare into each others eyes with deep longing.
I agree with Clary.
It is oddly intimate.
Jace is able to sense where Magnus lair is hidden.
And just in time.
The protective wards are down.
Circle Members attack, and the shadowhunters are able to save the day.
Magnus is impressed that Clary fights with her heart.
He agrees to summon the demon.
Shell also need a powerful rune burned into her arm to help face the greater demon.
Cue the screaming and sizzling sound.
Magnus instructs the shadowhunters to not let go of each others hands.
They must hold strong so you can maintain the demon.
Plus, the demon will want payment of some sort, but we dont know what.
Magnus summons the demon, and a huge black tornado fills the pentagram.
It has red eyes.
Kudos to the Freeform CGI department on this one.
(just read that last sentence with a sarcastic font.)
Immediately Clary sees her mom.
And Alec sees Jace.
Alec breaks the bond, and the tornado sucks Jace up.
Everyone tries to pull him out, but its no use.
Clary uses her seraph blade to kill the demon, killing her memories right along with it.
Its been an hour since Ive seen you.
Clary mopes around as Jace encourages her to bask in the glory of killing a greater demon.
They will find her mother.
Clary touches her necklace and sees Valentine leaning over Jocelyn in the weird bubble.
Then he looks at her and demands the cup!
Well that was unexpected.
We see Simon ignore the call as he stands before the Hotel Dumort with Camille smiling from the balcony.
Something tells me hes not back for another Bloody Mary.
