Jonathan is alive… but only briefly. He bleeds and calls for his mother, his blood forming a pentacle which summons a great big ugly demon
Hey, I’m with you demon mum, someone calls me unexpectedly in a morning will not get me at my best
Simon and Luke have noticed that Maia is missing and they go to visit the Seelie Queen (well first they visit Magnus who is all “excuse me, valentine, genocide, et al. Priorities”) who they have randomly decided is responsible (accurately but hey, Valentine is running around but you assume the Queen is at fault). She lets slip she made a deal with Valentine to get him out of the city and Simon and Luke pretty much spend the rest of the episode playing in the Seelie realm looking for Maia. This would be the magical fae realm of Plotboxia!
The Shadowhunters - well, Izzy, Clary, Alec and Jace since the rest of the Shadowhunters only exist in crowd scenes in the Institute. They fight the big demon which splits into a gazillion little demons which all run and hide. This is when Clary gets the news from Luke that Valentine has fled the city. They can’t take down the warlock ward against angel blood because it will let the demons out.
Wait… why… what?
They also decide people need to go to Idris to protect the lake from Valentine’s shenanigans. Yes there’s an army of Shadowhunters there but they’re ALL CIRCLE MEMBERS. Seriously like half the Clave is a circle member. Of course Clary and Jace go. Of course they do.
That leaves Alec and Izzy to stop the demons by closing the portal. For that they need a powerful warlock. Magnus you have been summoned, at least he makes it clear he’s not doing this for the Clave. They go to the portal, fight more demons and seal the rift. And by “they” I mean Magnus
So, to Idris where Clary and Jace discover that the army led by chief Clave member Malachai are all Circle members. No, really. I told you so. He makes a big speech about how the Downworlders are totally the worst and how Clary and Jace have to die - starting with Clary
We even pull out the sad music for Clary’s impending doom. I didn’t press fast forwards. I was tempted. To the shock of no-one, Jace activates his wondertwin powers and he and Clary kill everyone. How shocked
To the lake before Valentine (hey, is this a good time to remind everyone Valentine only knows about the lake because of Clary & co? Yes?) and Valentine appears and stabs Jace. Woe he’s dying. And dying. And still dying. And Alec is feeling it through his rune and oh he’s dying and dying and woe and DIE ALREADY
Look, absolutely no-one watching this thinks Jace is actually going to kick the bucket. Stop wasting your dramatic tension on this
So Jace is dead and Clary imprisoned and Valentine makes another speech about how he’s totally not a bad guy - and he summons the Angel Raziel
And I honestly expected better CGI. This is your angel, Shadowhunters do better! Valentine announces he wants all demons dead. And all Downworlders. And all nephilim who don’t support him (all 6 of them).
Raziel points out heaven is totally uncool with this - killing Nephilim is bad. Killing Downworlders (who have souls) also totally bad. Killing demons is cool though
Valentine doesn’t even pause on hearing this (fuck the will of heaven apparently) and plans to go for it anyway- because apparently if you cut yourself in front of the angel he totally has to do what you ask
