'Supergirl' Season 2 Episode 6 'Changing'
The previous episode starts with Environmental scientists who discover a wolf that contains an alien parasite in the Arctic. The parasite takes over Dr. Rudy Jones (William Mapother), while the rest of his colleagues die.
Meanwhile, Kara is trying to convince Mon-el (Chris Wood) to undergo training with her to become a superhero. She only convinced him after she had too much to drink.
Alex reveals an important personal detail
Alex (Chyler Leigh) finally opens up about being "gay." She explained her attraction to the same sex by telling her about her bestfriend Vicky.
Alex and Kara have a few misunderstandings after that conversation as Alex decided not to talk about her feelings about Maggie. But Kara assures Alex that what she felt was okay.
The Guardian arrives
With the help of Winn (Jeremy Jordan), DEO finds out who killed the employees. The footage shows that Dr. Jones has been infected before he attacked his colleague.
Kara becomes disappointed after she learned that Mon-el took a job as a "muscle for bookies," according to Yahoo. However, he is forced to stand up and help the agents to stop the Parasite after Hank or Martian Manhunter and Supergirl were both put into a coma by the Parasite.
Meanwhile, Olsen went to DEO to talk to Winn about the suit. This is why Guardian appeared in this episode. He and Mon-el fight the Parasite until Supergirl shows up. Supergirl beats the Parasite by overloading his draining power with the help of Plutonium 239. As mentioned earlier, Hank was in coma but worse than Kara's. M'Gann (Sharon Leal) was forced to give Hank a blood transfusion because Alex requested it. For more news and updates on "Supergirl", keep reading Gamenguide!
