Felt eerie watching this episode for multiple reasons… but join Tom Welling and Michael Rosenbaum as we revisit Smallville Season 5 Episode 10: FANATIC! After remembering when our guest star went full Britney by mimicking Lex Luthor this week we get a very pleasant visit from Kryptonsite’s own Craig Byrne! Bast from the past and a must-listen for any OG fans.
