That was definitely new information for her. That Magnus had been there when the vampire was turned. However, when he mentions that they're like siblings she can't help but turn fully toward him. "Really? My world's Alec and I haven't gotten to that point yet. Though I see both you and Izzy like family."

"You don't need to thank me, Alec," she says softly. "This is Jace we're talking about and I don't want him hurting." As for the mention of her brother being Jonathan, it just hurt her head. "Have you actually met my brother?"

At the mention of Simon though she can't help but smile," He's actually training with you all? Is he getting better?" Though that smile gets a bit wider," Okay, so we're hunters then. That's better than the alternative and it coming out."
