WAIT A MINUTE HOLD UP
All Herondale descendents have that angel star birthmark right???
Like, even Stephen Herondale had it.
Jace had it, but he would’ve had it anyway, because of Valentine’s experiments.
But now we know that this came from the descendents of Will and Tessa.
So can we assume that their daughter had it too?
Their daughter who married a Blackthorn?
Is Julian going to have that birthmark too????????!?!!??
