Mark Consuelos opened up to Andy Cohen on Radio Andy about the upcoming tribute to Luke Perry on Riverdale. The CW series' season 4 premiere episode will deal with the death of Luke’'s character, Fred Andrews.

Mark said that the episode will be a "tribute and will address the loss of the character Fred" and confirmed that Fred will die.

"It's heavy, particularly for series star KJ Apa, who plays Archie Andrews, Perry's character's son... They were very, very, very close. So I think to put it behind you a little bit and have some distance from it and then obviously having to deal with it now, it was interesting," Consuelos shared.

Previously, it was reported that Perry's Beverly Hills, 90210 co-star Shannen Doherty was joining the episode for an important guest role. Consuelos also confirmed Shannen Doherty's involvement in the episode but did not divulge any specific details about the type of role she'll be playing.

"I just know her [Doherty] and Luke were very, very close until the end," he said, praising series creator Roberto Aguirre-Sacasa for his "knack" for "putting together these pieces and getting people to come on the show."

Doherty's casting was announced at San Diego Comic-Con last week, with her role being said to be a significant one even though her screen-time may not be much. Her character will appear in the season 4 premiere, "Chapter Fifty-Eight: In Memoriam."
