Fans of Supergirl and fans of the Legion know there's something there between them, and it's gonna be a lot of fun to see the rapport between those two. We're not reestablishing their relationship that issue, per se, but instead, we're going to...
JR: You're giving too much away.
SG: Oh. Yeah, you're probably right. Well, uh, Supergirl/Brainiac 5 fans, give "Supergirl" #52 a read! [laughs]
And will you be exploring the Brainiac/Brainiac 5 relationship in "Last Stand of New Krypton?"
JR: Sterling had way more of a hard on to work with Brainiac 5 than me and I was the one that said, "You have to write the ultimate Brainiac vs. Brainiac 5 battle of wits and intelligence" And you'll see that play out in "Supergirl" #52.
SG: And what I think the best thing about that is that, in that equation, Supergirl is the X factor. I took what James said to me and said, "That would be awesome, but what happens when Supergirl is in the mix?" And you'll see that play out. It becomes a battle between Brainiac 5 and Supergirl versus Brainiac, and it's a big Braini-hullaboo.
