Sold to the Don, Now I Rule

Derek brings Lena to an underground auction as collateral for his debt; she steps forward and declares she is the old don's lost daughter.

In Marco's study, Lena fits her half-key to Marco's matching key, but Zia demands a DNA test and Derek threatens to burn the only letter from her mother.

Lena outsmarts Derek and retrieves the letter; on the way back a tampered car slams into a barrier, and the letter warns her to trust only Marco.

Lena disproves Carmine's forgery and demands a neutral retest; Carmine bribes the lab to swap the sample, but the scheme only ends in a leaked auction video.
