In the Season 3 episode of Supergirl “Schott Through the Heart,” after the death of Winn’s (Jeremy Jordan) father Winslow “Toyman” Schott Sr., he’s approached by his estranged mother Mary McGowan. Winn is suspicious because she abandoned him years ago. She explains to Winn that her husband warned her that if she were ever to make connect with Winn, he would kill Winn. Mary warns Winn, “You’re still in danger.” Now they must work together to stop a copycat Toyman.
