Synopsis:
Supergirl meets Karen Blair, a Midvale resident who despises the Girl of Steel. Supergirl forces Karen to admit the reason for her hatred, which is her belief that Supergirl killed her father.

Supergirl uses a chronoscope to view the events leading to Karen’s father’s death. On the same day Supergirl arrived on Earth, Mr. Blair was killed in his observatory by an object from space. Karen thinks it was Supergirl’s ship, but the chronoscope reveals it was a space bat lured to Earth by signals Mr. Blair sent from his observatory. With the truth revealed, Karen abandons her hatred for Supergirl.
