In time Kiwi or evrafter would have. I'd say the excitement for the crossover eclipses anything at the moment and normally discussions are not posted one week early.
Thanks for making this though
To be honest, im much more excited for the mid-season finale than the crossover. Im thrilled to see the continuations of the stories of mon-el, the legion of supe4heroes, and of course, reign.
To tell the truth, i think that the crossover came at a bad time for supergirl, because it ruin the momentum that the show got this week with mon-el's return and the awakening of reign.
