Thank you so much for posting this! Parts of this issue were some of the first things I ever saw on old S_D, years ago. *sniff* Brings back memories.
My, Lois fills out that Robin costume, doesn't she? Pictures of Robin!Lois would confuse Tim's sexuality to no end.
I think the only thing that would freak Clark out more that Bruce finding out, is Bruce finding out and offering an actual Batman costume for Clark to use. And possibly a real Robin outfit for Lois.
You just know Lois made up for Clark's discomfort with kinky sex that night.
