Chloe is in truth Lois, I don’t even think Lois would do something that suicidal.
Which Lois are you talking about? L&C's Lois was doing crazy, suicidal stuff all the time. She wasn't as foolhardy as SV's Lana but she loved to take risks.
I’m thinking that’s why I just want Lois to show up. I want Clark to be happy. Just a little bit.
If Lois shows up in Smallville (and isn't Chloe) she'll probably be Lex's girlfriend. Smallville's PTB envision Lois to be in her early twenties, maybe still in college - she'd be too old for HS Clark.
Plus there's the precious Clana to think of...
