J.C.'s box was a box that Jocelyn Fray kept items of Sebastian Morgenstern's baby years.
Description[]
It is a silver box with the initials "J.C." printed on it. It houses a lock of Sebastian's baby hair, some photographs of him and his baby shoes.
History[]
Over the years, Jocelyn was often seen holding the box on the anniversary of Sebastian's birthday and crying over it; in mourning of the child that she lost to Valentine's experiments.[1]
At some point, it came into Sebastian's possession for unidentified reasons. He later left it in Amatis's house as a calling card for his mother to find.[2]
It is currently at the bottom of Lake Lyn, after Clary threw it in there to scatter Sebastian's ashes along with his Morgenstern ring.[3]
