Supergirl S3E19

Things that happened:

• Sam is taking care of Ruby and helping her deal with everything.
• J'onns is still dealing with his fathers declining condition
• James was held at gunpoint as guardian and deals with racism 
• Corville is back!

Top Moments:

• Lena is still trying to help fix Sam. Kara is dealing with Lena not trusting Supergirl. A mysterious girl comes with Covile journal and information about the cult. Catco is attacked.
• James as guardian is able to save the girl after the cult kidnaps her back and the police show up. Alex and J'onn take Ruby and M'yrnn to the arcade. The cult threatens to reveal Guardian.
• The arcade backfires. They find out that there is a stone that can make a world killer and it might be able to reverse the process on Sam. James is going to hold a press conference.
• The girl turns her self over to the cult and Mon-El goes with her. The cult is able to make the stone and signal for Kara. Olivia becomes a fourth world killer. They get the stone from her.
• The stone is no longer functional but they locate a meteor with the rock. Mon-El and Kara are going to travel to get the stone. Reign is adapting and the kryptonite is not as effective. 

Predictions:

• Hopefully this rock will be able to reverse Reigns affect on Sam so that we can get her back.
• I think there is a possibility that Lena might find out Karas secret.
