Quick recap
Mari McCabe, raised by adoptive parents in Detroit, wears a necklace from the birth family she never knew. She learns it's the Tantu Totem, which grants her the abilities of any animal. When she starts using her powers, the Flash and the Arrow show up in Detroit thinking she's a threat, with Cisco and Felicity helping investigate. Mari is hunted by people after the totem and finds out the one behind it is Kuasa, a sister she never knew she had, raised in the family's village in Africa. Mari travels to her homeland, faces Kuasa, keeps the totem and decides to use her powers as a hero: Vixen.
