Hi Virginia,
Thanks for the FDK!
They weren't married in canon.
Clark didn't see Lex enter the newsroom. He was otherwise distracted.
Nigel will call in the tip and specify that their best reporter - Clark Kent should be sent.
From what he had observed, he knows that Lois is under the influence, but that Clark doesn't seem to be. When he saw him striding up the ramp he saw a man on a mission and not distracted by thoughts of love.
