Glitch is Lavender Eyes's Unlucky Childhood Friend
Think about it: he was apparently devoted to her, was implied to have known her when she was younger, and seems to be very protective of her daughter.
 * On my first viewing I kind of assumed Glitch would turn out to be DG's dad. He and LE have major chemistry. Plus, both of the girls look a lot more like him than like Ahamo. When they played the creepy-pedo-father angle again with Ahamo, it felt like a weird echo of the Glitch encounter, leaving me convinced for a while that Lavender Eyes/Glitch was the original intention and Ahamo was written in later.
 * You are not the only one who concluded this very early in the storyline. I was disappointed... I love stories where you get to befriend your parent(s) before you know they're your parent(s).
