Hi,
Clark has such bad timing, and I'm sure it would have to be a an epic disaster for him to leave right at this moment.
Unless he heard the emergency actually happening, a couple of minutes wouldn't make much difference. If he'd just waited to give Lois a smile of encouragement as she started her eulogy.
I'm not sure Lois will forgive him for running out at this moment, and I really wouldn't blame her.
Even telling her his secret might not be enough in this instance.
So, I hoping you're going to write him a really excellent reason.
Yours Jenni
