Question: does the ex wife die in taken 2

Answer: No, Leaving Kim at the U.S. Embassy, Bryan uses his memory to find Murad's hideout. He rescues Lenore and pursues the surviving mobsters to a bathhouse, where he kills them. Confronting Murad, Bryan offers to let him walk if he agrees to return home and cease his desire for revenge. Murad agrees and Bryan drops his gun, but the former goes back on his word and tries to kill Bryan, only to find the gun unloaded. Realizing that Murad will never drop his vendetta against him, Bryan kills him by impaling him onto a sharp towel hook.
