Smallville - Season 10 Episode 5

Oliver enjoys his new, public role since he outed himself as super-hero, yet misses Chloe desperately and feeling guilty. His example further inspires Clark to tell at least Lois, but just when they meet to that end an Egyptian jewel allows the Pharaonic goddess Isis to take possession of her body, eager to resuscitate her beloved Osiris, all required being at hand from a major exposition in Metropolis, but that would also revive his realm, hell, on earth. Tess, who is otherwise preoccupied with Lex's boy-clone Alexander, joins Oliver and Clark at Watchtower, where she proves herself able to fill in for Chloe IT-wise. Even with that invaluable research, Clark nearly perishes in his supernatural duel with Isis. Cat get caught in the fight and mistakenly believes Lois is the evil Blur.
