Fumes

They say he lost half of his braincells as a child because he liked to inhale incense and geyser steam.
He claimed that the tendrils soothed his lungs and it became an odd habit.
His mother named him Dentist -- she always wanted one of her children to do something in the medical field -- but his father affectionately deemed him 'Fumes' after learning about his peculiar ways.

He doesn't think much and when he does think it looks like he's straining to form an opinion about something. He desperately wants a family despite having no redeeming qualities or the capacity to care for children. His mother detests his new love interest, Gag. She complains about her sons love life to anyone that will listen.
