Just right.
At first I, too, thought that Lois was being really dense about the initials, but it soon became evidence of just how depressed and obsessed she was. She really was 'not herself.' And I loved that Clark was brave enough to make a pretty dramatic move to get them both out of the funk they were in. And thank you for not giving in to the temptation to send them straight to lovey-dovey land. That's not what Lois needs at this point. She just needs to get her old self, and her old friend, back again. She'll have time for the rest later.
Well done!
