It's probably one of the best episodes of the season so far! Here's a recap!
"Blood Memory" is and could be one of the best episodes of the season; let alone one to remember with it's a well-written story about Nia; the connection of her family and the Dreamer powers. The character of Nia was really the focus character in this episode; as Kara and Alex were second in the way this episode proceeds. Nicole Maines gives her best performance so far and I would really consider that she should get a nomination for awards.
Kata and Alex's relationship aren't what it use to be now with Alex not knowing that Kara is Supergirl and even doesn't know what Kara's favorite movie: The Wizard of Oz. There is a spilled conflict between the characters; I'm very interested to see how this will play out.
Meanwhile, the copycatted Supergirl has run into what seemed to be health problems. After trying to revive her with the shock paddles, some of the electric went around the world creating alien rage pills in town. Later at the end, the commander calls for assistance in the United States, I wonder who?
Overall, I give this episode a 9/10.
You can catch Supergirl Sundays at 8/7c on The CW.
