I can see why a lot of people think Lana ratted Lois and Clark out, especially since she was at the funeral. I admit it is a possiblity. However, I don't really think she did. When I started reading this story, I was expecting Lana to blow her top when she

(1)Found out her boyfriend had female roommate.
(2)Found out what happened at the cabin.
(3)Found out Clark had to get married.

But, although she was upset all a of these, she didn't act irrationally, particularly for an 18 year old girl.
And contrary to what most readers expected, she DID NOT encourage Clark to have an affair with her once Lois and Clark got married, behoynd the first time Clark to her they were married. (And I think her emotions were understandable, in that situation.)
As for Tim, she thought Clark had betrayed her. What else was she supposed to do?

To conclude, although I don't want Clark with Lana, I don't think she's a bad person. And that means I don't think she told the media on Lois and Clark. (particularly considering she believes Christopher is Clark's baby.)

Who did?
Nanvace has a lot of resources and people working for him, so it could easily be one of them. We haven't seen Mindy in a while...?

I think it's nice that Lois and Clark were getting closer in these parts (because of Clark's loss), but it worries me.
It sounds to me like he's kissing her because she's there, she's a woman, and he's feeling low. It's realistic, especially giving the circumstances, but it's likely to give Lois a false sense of security. And Clark will withdraw again when he realizes what happened.

Of course, it's a good idea to look to the one you love for comfort, and it can be a bonding process, don't get me wrong. But I don't see that happenening here.
