In my opinion, Louise projected herself and Rudy in a mother/son role because Louise's long history with romance in the show is'nt exactly nuanced, in fact it's a bit slap-happy…just ask Boo-Boo and indeed Rudy. I also don't think she wants to tip her parents off to notions she has of liking someone. Still, her speech…

What about it? n52 Superman is also on the cover of that, is he going to appear? NO

She does'nt need to come back, there's already a Lois Lane in the books, the REAL Lois, married to Superman and raising a kid
