Degrassi: the Next Generation
Mr. Raditch reappears after many years in Mother and Child Reunion (1), where he is showing Toby and Jeff Isaacs around the school and discussing Toby's enrollment. When Toby stumbles across his friend J.T. Yorke, Raditch tells them they will continue in his office.
In Mother and Child Reunion (2), Raditch is seen greeting people outside the steps of Degrassi and welcoming them to the reunion. During dinner, he introduces Caitlin to the stage. After the fight between Joey and Keith, he tells the group that it is time to dance.
In Friday Night, Raditch told Ms. Kwan's Grade 8 English class that she was taking a leave of absence due to severe stress and that he would be filling in for her for the rest of the semester. When Terri MacGregor asked if she was alright, Raditch explained that her husband was extremely ill and this, coupled with her workload, had proven too much for her. As Jimmy Brooks and Spinner Mason had egged her car the previous night, they felt extremely guilty.
Due to Ms. Kwan's continued absence, he also served as the Grade 8 class homeroom teacher in Cabaret.
Marco and Alex tried to reason with him so that he would expel Rick for putting Terri in a coma in Don't Dream It's Over. It occurred to J.T. and Liberty that he didn't help the students deal with the school shooting and Rick's death, and that he would not let J.T. and Liberty put on the violent version of Dracula, causing them to write the Radish song in Voices Carry (2). This is also the episode when J.T. and Liberty became a couple so technically since Raditch gave them detention, they wouldn't have gotten together without him. After Rick's death, Raditch got fired from being the principal of Degrassi after proving he can't properly deal with the school shooting.
