They met two or three times. Marcus got obsessed with him and kept turning up to his house drunk and uninvited. SG told him to duck off and leave him alone, and never come round to his house again. Marcus made some thinly veiled comments about outing ‘a closet bleep’. When he died, Marcus was banned from the funeral by SG’s family. Ever since he’s been obsessing over him, highjacking the family’s grief, has outed him (he was known as straight), knowing SG’s daughter is on Insta, and behaving in a disgustingly disrespectful manner.
