Micky Maguire started out as a paranoid, aggressive, violent man who followed in his brother's footsteps but his acceptance of his secret homosexuality made him into the kindest member of the Maguire family. He had a brief and casual relationship with Ian Gallagher just after his first appearance on the show, which being his first gay experience left him with strong feelings for him. Their relationship may have blossomed into something more meaningful but Ian was disgusted when he heard how Micky had his dog Nelson give him oral sex when he had broken arms.
