The New Adventures of Superman: And the Answer Is...?

Jace, a blackmailer, with Tempus' diary, finds out about Clark's identity and forces him to steal and do everything more than he wants...and one thing more (by Nigel's suggestion).... to kill Lois, or he kills Martha and Jonathan. Lois tells Clark the only way to save his parents is to freeze her, then she will look like a dead person, and he tells her this can be very dangerous to her life, but, even so, she tells him to freeze her.
