SMALLVILLE – "Patriot" (8:00-9:00 p.m.) DC COMICS CHARACTER AQUAMAN RETURNS WITH HIS WIFE MERA; TOM WELLING DIRECTS AND MICHAL HOGAN ("BATTLESTAR GALACTICA") GUEST STARS AS COL SLADE. – in an effort to protect the rest of the team, Oliver (Justin Hartley) decides to register for the Vigilante Registration Act to see what the government plans to do with the new law. As he suspected, it was a trap to lure superheroes to an undisclosed location where he is confined to a jail and subjected to a battery of brutal tests under the supervision of Col. Slade (guest star Michael Hogan, "Battlestar Galactica").
Seriously, Michael Hogan! Col Tigh! When can Supernatural get him to guest star? Want it so bad I can weep.
