You was Clary's younger cousin, you would see Simon every time that your family visited your aunt and cousin. So it was best to presume that you and Simon got along well. Since your last visit,a lot had changed for Clary and Simon so since clary had Shadowhunters things to do that she didn't want you to find out about, you was now hanging out with Simon who looked more paler then you remembered."I'm not ill,I'm fine. It's a new skin care" Simon said covering he was in fact a vampire to you.
