"Why had she done it?"
She wouldn't have. And neither would he.
I've never been able to buy into the 'Boo hoo, our best friend has just been killed, let's have sex' scenario. Comforting each other in a time of mutual grief (and Clark is grieving here also) is one thing, but this is over the top and out of character for these two.
They each have a strong sense of right and wrong, and no matter how much they may have been hurting, or how much they may have been drawn to each other, neither would have taken advantage of such a situation. It's not in their character.
