No, seriously: in her 84+ year history, who are Lois Lane's friends?
Not the family she came from:
dad Sam, sister Lucy, and sometimes mom Ella.
Not the family she made:
husband Clark, son Jon; in-laws Jon and Martha, Kara, Krypto.
Not the friends who are mainly Clark's:
Jimmy Olsen, John Henry Irons. Conner, Mon-El, Power Girl, Lana Lang.
Her own friends? Cat Grant isn't a friend, much more of a rival,, Perry White is her boss Not her friend.
Is Lois Lane friendless?
Let's fix that.
Who can be Lois' platonic friend(s)? Someone(s) who is not friends first with Clark.
I'll start the Nominations.
My top pick for Lois Lane's best friend is .... Selina Kyle.
I'd either start in-continuity by having them talk and hang out a lot without Clark or Bruce around.
Or any new Superman project (movie, show, cartoon, video game, etc), establish that Lois and Selina have been besties since high school despite living in cities separated by a bay (think San Francisco and Oakland).
