Luke is Caucasian.[1] | Luke is black. |
Madame Dorothea was Jocelyn and Clary's older neighbor who had little interest and relationship in the two.[1] | Dot is much younger than Dorothea in the books, is Jocelyn's assistant and is like a sister to Clary. |
Maureen Brown was a young fan obsessed with Simon.[2] | Maureen is slightly older, around the same age as Simon and Clary, and is friends with them. |
Clary playing with a faerie as a child was what convinced Jocelyn to take her to Magnus to get her memories taken.[1] | Clary was attacked by a demon while playing by a lake. |
The only sign that Clary's mind block was starting to fade was that she was starting to see the Shadow World for what it was, and it was past her scheduled appointment with Magnus.[1] | Much like in the movie, Clary began drawing elements of the Shadow World and being a Shadowhunter, like runes and demons. |
The New York Institute at that moment in the story was only inhabited by Jace, the Lightwoods, and Hodge Starkweather.[1] | There are several occupants at the Institute carrying out missions. |
Shadowhunters don't really use technology and gadgets and primarily rely on their Sensors to track demons.[1] | The Institute is much more modern and has several computers and high-tech equipment, some of which is used to track demon activity. |
The demon Jace, Izzy, and Alec followed into the Pandemonium was an Eidolon demon that was preying on mundanes in the guise of a human boy.[1] | The demon they followed was a shape-shifting demon they tracked because several demons have been killing mundanes and draining them of blood. These killings have also not gone unnoticed by mundanes and became the center of an investigation by the NYPD—one that Luke was a part of. |
Simon's band consists of three other male members.[1] | The band consisted of just Simon and Maureen. |
Eric performed at a poetry reading at Java Jones, and Clary and Simon went to support him.[1] | Simon and Maureen performed as a band. (In an early draft of the script, Eric was mentioned as a band member, or a potential recruit, who'd backed out.[3]) |
It was Eric who has a van that they use for the band.[1] | The van is Simon's, which Clary spray paints with their band names for them. |
Clary first saw Jace inside the club following the demon.[1] | Jace bumped into Clary outside the club, and the encounter was seen by Simon and Maureen, both of whom did not see Jace and thought Clary was talking by herself. |
The Circle had no interest in mundane blood. | The Circle had demons draining mundanes of blood to be delivered to them. |
Magnus Bane has no connection to the Pandemonium Club in New York City. | Magnus Bane is the owner of the club. |

Clary simply shouted a warning at the demon when Jace was about to kill it.[1] | Clary came up to them and pushed the demon out of the way, putting her right in the middle of the action when the fighting commenced. Clary even got hold of a seraph blade, which activated in her hand, and killed a demon that Jace pushed into it. |
Clary ran into Magnus coming out of Madame Dorothea's apartment on her way to Java Jones.[1] | Clary bumped into Magnus on her way out of the Pandemonium. |
Jocelyn never got around to telling Clary anything about their past before the Circle members came for her. Clary was still at Java Jones when the Circle took Jocelyn.[1] | Jocelyn managed to give Clary a stele, a magical necklace, and some hints about her past. Clary was home with her when the Circle members came. |
Dorothea was minding her own business in her apartment when Jocelyn was taken, though she did warn Jocelyn beforehand about whispers of Valentine's being in New York.[1] | Dot helped Jocelyn face the Circle. It was Magnus who called to warn them about the Circle. |
Shape-shifting demons are called Eidolon. | Shape-shifting demons are called Ravener demons, which are also a very different kind in the books. |
Clary rushed home from Java Jones before she was attacked by a Ravener demon. When she woke up three days later, she called Luke, who told her not to look to him for help. Later with Jace, they accidentally Portaled to Luke's house from Dorothea's because it was the last place Luke used the Portal to get to. Clary overheard Luke's conversation with Circle members.[1] | Jocelyn and Dot intentionally sent Clary to Luke at the precinct through the Portal. There, she overheard him talking to the Circle about not caring about them. It was then that she rushed back home and was attacked by a Ravener demon in the guise of Dot. |
Clary killed the Ravener demon that attacked her in their apartment.[1] | Jace was the one who killed the demon. |
— | Clary received a Portal shard necklace from Jocelyn that gave her visions. |
Clary and Jace found Simon lurking around Luke's house, which he did because Luke was making up excuses about Clary having been missing for the past three days.[1] | Simon tracked Clary's phone to the Institute with an app after she has been missing for two days. |
Most runes are black and only work once, after which the ink will fade (to a whitish scar) and would have to be reapplied. | Most runes are red (this has been changed to black in the second season) and also fade to a pinkish burn-like scar.
