As Brainiac was describing his thought processes on how he deduced where Leviathan would be headquartered, he pointed out the symbol which he said was on "this building's cornerstone". That wasn't a cornerstone. It was a pillar. A cornerstone is the first stone laid in a masonry building to make sure it's square and stable. A pillar is a support for an overarching structure.

What an episode
19 November 2019 | by leahdreySee all my reviews

The acting in Supergirl especially with the main cast is incredible. And after this episode i can safely say that the acting was better than in the movies. Katie mcgrath and Melissa need to have all the awards. Not only was the writing of this episode fast paced and interesting but i found something special here that i have been waiting for in a hero show. The feeling of something greater than ones self. Kara learns the truth about Lena in the perfect way. These writers are poetic and smart . A super and luthor at odds trying to avoid the history between their families while facing trauma caused by the others lies and deceit ? If the show keeps up their momentum and follows through on the points they are making . I believe this could be the most important show on TV right now. The "drama" did not feel like empty entertainment but something bone chilling and surreal. The themes this show is portraying , love, hate, betrayal, and forgiveness are important for people to see. Overall an amazing episode , if you are wondering if you should watch supergirl i would watch it just so one can truly experience the gravity of this episode in its entirety.
