Smallville :

Clark finds Tess in Lana's ransacked apartment and realizes Lana is missing. Tess tells him Lex is still alive and may have kidnapped Lana and finally reveals the truth about what happened to Lana after she awoke from her Brainiac-induced coma. She informs him that Lex had her taken into custody when she woke up, and forced her to break up with Clark via a video. Believing that Lana has been kidnapped, Tess tells Clark that she believes Lex took her. She also informs Clark that the reason Lana left after coming out of her coma was because Lex had her taken into custody when she woke, and forced her to break up with Clark via a video. After Clark talks with Chloe, he realises that Lana didn't return as she was busy plotting her revenge against Lex.

Clark and Chloe discover that Lana hasn't been kidnapped, but intends to use Lex's 'Prometheus' technology, which harnesses alien DNA and gives individuals super-human abilities and inflict it on herself. Soon Lana is imbued with super-powers of her own. She tells Clark that he no longer has to worry about her, and that they can work together to make the world a better place. Meanwhile, Tess breaks into a secret LuthorCorp facility and is shocked at what she discovers.
