Showrunner Roberto Aguirre-Sacasa announced that season four will kick off with a tribute episode to Luke and his character Fred Andrews.

Luke‘s last appearance on Riverdale aired back in April and the absence of his character has not been addressed on screen yet.

Luke passed away in March after suffering a stroke.
