Annette O'Toole returns to "Smallville" as Martha Kent in February 11 episode. Clark is surprised to see Martha on the news speaking at a pro-vigilante rally. However, surprise quickly turns to horror when he and Lois watch as Martha gets shot on national television.
Meanwhile, Lionel reveals himself to the world and reclaims LuthorCorp from Tess and Oliver. Lois and Chloe decide to cheer Clark up by showing him videos from thousands of vigilante supporters professing their support for The Blur.
Executive producer Brian Peterson recently said in an interview with IGN that this episode called "Beacon" is "a really great, inspirational episode" and is "kind of the run of him [Lionel Luthor] trying to reunite his family." Speaking of the return of Lionel, Brian teased, "He's got a great scene with Annette O'Toole coming up and he's got a really nice arc with Tess and also with Clark."
