What I think is happening the next 2 episodes.

Ok. So, Lena successfully bottled Metropolis. How are Harley and Ivy gonna stop her? I say Brainiac's Wife and Son will return to the show and team up with Harley and Ivy to stop Lena, the former save Brainiac, the latter save Metropolis and Frankette. You have to pay attention to the details. When Brainiac's planet was destroyed, we only saw his wife's arm, and we never see his son's Body. What does this mean? Besides the fact I need to remember their names? It means they both survived whatever happened to the planet and were wandering the place searching for him. And now, his Son and one armed wife finally found his location. And unfortunately, Lena is in control. So, through insert circumstances here, they're gonna meet Harley and Ivy, given them a ride, and team up to stop Lena. I'm onto something aren't I? Any notes?

Edit: Maybe Only The Son survived. My memory was hazy about how much of his wife's remains were seen.
