I'm new to this website, but have always loved the show and have been reading the fan fictions for a while now. But recently, I was rewatching a couple episodes of the show and I was wondering when or if Clark told Lois that he was adopted (before she found out his secret). I know that in Strange Visitor (From Another Planet) he was writing an article about adoption and hinted at being able to relate to the topic but I don't think Lois really knew that he was. So was it one of those things that she only knew when she found out his secret or did he tell her before that?
This is probably a stupid question but I've been thinking about it for a while and couldn't find the answer anywhere online.
