novel. After Jace's challenge, Alec kisses Magnus in front of all the Shadowhunters in front of the Clave when they were choosing partners for the battle in City of Glass, (however in the TV adaptation of the novels, Alec revealed this by kissing Magnus in the middle of Alec's arranged marriage with clave representative Lydia Branwell and revealed his association to him and his sexuality). Also, when Clary cast a Rune that made her look like the person the onlooker loved the most, it is implied that Alec saw Magnus.

Magnus confesses that while he still loves him, they are through as a couple. Magnus shares one final kiss with Alec before walking away from a tearful and heartbroken Alec.
