A look at tonight's sci-fi TV:
Dollhouse, "Getting Closer" – The rush to the Dollhouse series finale starts tonight with the return of Summer Glau as Bennett and Amy Acker as Claire "Whiskey" Saunders. Topher is tasked with rebuilding Echo's original personality after Adelle learns that it's the key to stopping Rossum's blanket brain invasion plot. Elsewhere in the episode, Bennett's dark relationship to Echo is revealed, Boyd paints the walls with Rossum exec blood, and the corporation's mysterious leaders come out to play. (9 p.m. on Fox)
Batman: The Brave and the Bold, "Aquaman's Outrageous Adventure" – In a genius move, Cartoon Network's smart and campy new Batman show has decided to depict Aquaman as a dumb, egocentric brute. It's hilarious. So tune in for some subversive superhero fun. (7:30 p.m. on Cartoon Network)
