Supergirl (2015)

S4E10 Suspicious Minds

Colonel Haley is furious when Supergirl answers a distress signal from a Navy vessel, only to discover it was a trap set by aliens. Announcing the site as DEO jurisdiction, she orders Supergirl to back off. When Supergirl stands her ground, Haley shifts her strategy to uncovering Supergirl’s true identity, starting with interrogating DEO agents, including Alex. At the same time, Brainiac-5 attempts to encourage Nia to accept her emerging powers, but she mistakenly thinks he has ulterior motives.
