The Dangerous Way Supergirl May Have Just Revealed Reign's Identity

Here's what happened. Lena told Sam to take time off to deal with her current problems, and Sam decided to take Ruby ice skating. Unfortunately for poor Ruby, Reign had a mission to retrieve a second Worldkiller, and Sam had to go do villain duty, which resulted in her abandoning her daughter at the rink. Ruby called Lena for help, and Lena kinda sorta spilled the beans that something is wrong with Sam.
