Well there seems to be big plans for Kendra next year. She has a connection to the Totality, where those answers are going to be searched in Thanagar Prime with John Stewart and Martian Manhunter included. Since John is going to be there, looks like he's going to get some answers as well. Hopefully we'll find out why he has the connection to the UV and how his new ring got formed out of nowhere. I don't see Kendra being swapped. I questioned it, because Snyder is a fan with John and Shayera.
