I’m not sure if this is a good thing or bad thing. I guess I said back in. S1 that bringing Lex around in Season 4-6 might be ok.
like Superman he tends to bend and warp things around him.
same reason putting Joker in Suicide Squad was a bad idea.
but Lena is well defined. Supergirl is about as Gelled as they can get. So shaking up Lena w Lex might not be bad. I just hope they don’t over use him.
