Wild cards Time for another wild card lightning round. DC Super Hero Girls (Cartoon Network, 8 a.m., season-two premiere): These teenage superheroes returned last week as part of the Space House alongside the similarly teenaged heroes of Teen Titans Go!, but this marks their proper re-entrance onto the television landscape. U.S. Gymnastics Championship (NBC, 7 p.m.): Bring on the GOAT. 43rd Annual Kennedy Center Honors (CBS, 8 p.m.): Wanna watch Kelly Clarkson make Garth Brooks cry? Brooks, Joan Baez, Midori, Debbie Allen, and Dick Van Dyke will all be honored, but Kelly’s powers will be aimed right at Chris Gaines.
