Just a friendly reminder that...this is accurate except for the part about Jace having the same grandparents as Alec, Izzy and Max. Jace's grandparents are Tessa and Will and the other 3 are Cecily and Gabriel.
MINDBLOWN. Tessa ( not immortal from Infernal Devices) was seen talking to Magnus ( who is immortal so was in Infernal Devices and The Mortal Instruments) in the 3rd Mortal Instruments book City of Glass even though they are set 100s of years apart!! HOW?!
