Article arrow_drop_down

Mean Girls’ Jonathan Bennett who also appeared in the popular Smallville episode “Blank” will be guest starring in Supergirl Season 4! The actor announced this through videos on social media.

His character is known as “Quentin.” Here’s how The CW describes the character:

Quentin is a wide-eyed government attaché who is grateful when Supergirl saves his life. However, when he shows his true colors by attending an anti-alien rally, Supergirl aims to prove to Quentin that not all aliens are bad.

On Smallville, Bennett played Kevin Grady, a “meteor freak” who could make people forget things. Among the things he was able to erase was Clark Kent (Tom Welling)’s memory of who he really was.

Jonathan Bennett’s Quentin makes his first appearance on Supergirl in Episode #4.14 which is called “Stand and Deliver.”

Supergirl returns with new episodes Sunday, January 20 on The CW. See some photos from the return episode “Suspicious Minds” here!
