Well I’m through the second book now and I thought I would do this again, though honestly if I keep this up these are going to be a jumbled mess between the different seasons. Plus I know there are some major plot points between the show and the books that are completely different. So if something happens during the show that didn’t in the books I’ll put it in the minor details/differences section though some of them are not minor things.
Since I will be talking about plot of the book and show there is will be spoilers. Also if you want to see my previous ones check those out below:

- The Mortal Instruments: City of Bones | Which One was Closer to the Book: Movie or TV Show?
Jace in the Silent City
The first main thing that happens is Jace is sent to the Silent City where he is being held for trial. This event happened in both the show and book, but for very different reasons. In the book, after Jace let’s Valentine go with the Mortal Cup he back talks Maryse Lightwood and Inquisitor Herondale. They send him to the Silent City over night where the following morning he is to be tried by the Soul Sword to get the truth on what happened at Renwick.
In the show, after Clary rescues him from Valentine’s ship and Jace helps save Alec, who is dying after trying to find Jace, Jace is attested for aiding Valentine against the Clave. He is tried and sentenced to spend the rest of his days in the Silent City dungeons. He also sees Hodge again who was alive at the time also being held in the next cell over.
During the night (in the book) Valentine arrives and slaughters all of the Silent Brothers. He steals the Soul Sword but leaves Jace behind in his cell. In the show, Valentine also comes to steal the sword but Jace is freed from the cell. Hodge is finally killed and Jace saves another Shadowhunter instead of running after Valentine. This allows him to leave the Silent City and return to the Institute. In the books, Clary, Izzy and Alec rescue him then Jace is placed under house arrest with Magnus Bane as his caretaker. Jace in the show does stay with Magnus as well but after he doesn’t feel welcomed at the Institute anymore; however, no one is forcing him there or expecting him to appear in court later like in the book.
Oh this scene, one of my favorites from the show… has a whole new meaning in the book. There are lots of differences. For starters Isabelle joins them and Simon is still human. Also Jace and Clary still believe they are brother and sister.
Clary is also far easily tricked by the seelies and almost is killed twice in the books. The first time she almost goes off dancing until Jace stops her and gives her a mark to help keep her from being drawn in. You also see the court for its devilish ways in the book, whereas in the show it’s only hinted at. The second time she almost drinks from a cup given to her by the Queen, but again Jace stops her. However, Clary is later bitten by a fairy and sucks on her finger which just so happens to have the drink on it causing Clary to become trapped at the court. The Queen will allow her to leave if she kisses the person she most desires. Simon immediately kisses her then they all go around talking about who’s going to kiss who as it didn’t work. Finally Jace and Clary kiss, and Simon takes off not waiting for the kiss to finish as he’s furious since he was dating Clary.
In the show, Simon killed some bugs which made Jace and himself trapped in vines that are straggling them to death. The Queen will allow them to leave if Clary kisses the one she most desires. Now she knows Jace is not her brother and has been dating Simon for a few weeks or month at this point, so her kissing Jace is just a matter of choosing which guy she likes. Not forbidden or something she’s repulsed by as it was in the book. Clary first kisses Simon then kisses Jace. After the vines release the boys, Simon takes off. Also Simon is a daylighter at this point in the show, and the Seelie Queen wants Simon to join her and states that Shadowhunters always choose their own kind.
Simon Becomes a Vampire
After the Seelie Court, Simon in the book goes to Hotel Dumort where he is drained of blood. Raphael brings him to the Institute but cannot enter as it’s holy ground. They immediately go to a Jewish cemetery and bury him so he will become a vampire. Alec, Magnus, and Isabelle are all there in the book to see Simon reborn as a vampire. Magnus is the one who brings blood for Simon not Raphael.
In the show, Simon is turned into a vampire within the first few episodes. He is sired to Camille, Magnus’ ex, instead of Raphael like in the book. Clary also has way longer to debate on what to do. Also there wasn’t really a choice in the book, it was bury him or he’ll remain between life and death forever but never able to wake or get better.
In the show, after Valentine gets the Mortal Cup he starts using it right away to start turning humans into new Shadowhunters. In the process killing hundreds of people. They all stay and train on a barge somewhere in the channel of New York City, glamoured so no one can see it. Jace also has joined him shortly after he’s done this and believes he has demon blood as he thinks he’s Jonathan Morgenstern not Jonathan Herondale. Jocelyn is also awake by this point.
In the book, Valentine does not have a new army of Shadowhunters. Instead he has an army of demons that he is commanding using the Mortal Cup and Soul-Sword after drenching it in the childs’ blood of a werewolf, seelie, warlock, and vampire. Jace goes to the boat after getting a motorcycle from Raphael and spots it while he is flying over the water. Jace asks Valentine about his blood and is told it is just the blood of the angel. Considering he’s also holding the Soul Sword it’s revealed way earlier that Jace has angel blood, though it’s not taken the same way as it went down in the book. Also Jace leaves the boat and does not join Valentine at any point.
Simon is Kidnapped
In the show, Valentine kidnaps Simon before he became a daylighter to get Clary to come back to the Institute so she will touch the Soul-Sword in order to activate it so he can use the sword to wipe out the Downworlders (vampires, werewolves, seelies, and warlocks). Jace and Clary both go to the Institute as they believe since Jace has “demon” blood he’ll be able to destroy the sword. Jace glamours as Clary then saves Simon’s life… since Jace actually has angel blood not demon this makes Simon a daylighter. After he knocks out the guards trying to make Clary touch the sword, and then he touches the sword that is wired into the Angelic Core of the Institute. Thus activating the sword and killing numerous downworlders including Alaric (who in the book died at Renwick). More happens immediately after this… but it’s not in the book so I’m going to hold off on that until we get to that at some point (next book?).
In the book, Valentine after Jace leaves him kidnaps both Maia and Simon to complete the conversion of the Soul-Sword. He also doesn’t take them to the Institute but rather to his boat filled of demons. Nor does he face-time Clary to show him cutting Simon’s throat open as he does in the show. Magnus helps them get past the wards of the boats so they can rescue Simon and Maia. Simon’s neck was already cut by the Soul-Sword by the time they arrived. After fighting hundreds of demons and falling through the ship, Jace finds Simon drained of blood but not completely so he gives Simon his blood so Simon wouldn’t die. Similar to the show Simon almost kills Jace by drinking too much blood. And in doing so becomes a daylighter.
