I'm writing a story in which Clark and Lois meet as teens. I begin to wonder if Lana and Lois could become friends if they met as teens?

What do you think? Can't wait for your opinion.

Personally, I don't see why not. It's all in how you write it.

If you're writing your own story, you can make Lana as likeable as you want. In fact, Terry Leatherwood and several others have written stories in which Lana is portrayed very kindly (or at least so that we can understand her and sympathise with her).
