By giving her everything he has, he overloads her ability to contain both Kryptonian and human essences, causing her to implode. For a few agonizing moments, Clark is seemingly dead, his body gray and still.

She connects with her Bizarro doppelgänger, using empathy rather than violence to weaken Ally’s hold on reality. Meanwhile, Jordan uses his emerging powers to help rescue his mother, showing how much he has grown. superman & lois s02e15 aiff
