Kitty

Kitty is the slash ship between Ty Blackthorn and Kit Herondale from the The Dark Artifices fandom.

Canon
Ty had snuck out of the house to follow Julian and Emma while they were questioning Johnny Rook. He broke into the basement where Kit was. Thinking Kit might attack Julian and Emma, Ty attacked him, holding a knife to his throat and demanded answers. Kit was struck by how beautiful Ty was, especially his eyes. Julian and Emma, hearing the noise found the two and all three shadowhunters were forced to leave.

Later after his house was attacked by demons, Kit is brought to the LA institute where they reveal that he's a shadowhunter, specifically a Herondale. Kit locked himself in his room at the institute, not really accepting his shadowhunter lineage. Ty waited outside the room, saying he was protecting him, in case anything happened.

Fanon
Shipping between the two began immediatly after the release of Lady Midnight. Despite there being only two major interactions between the two.
