I was not expecting the suggestion that Kent forgive Lana. It really works for who he is, though. Here in the comments we've all been assuming she's evil and vindictive, and maybe she is, but maybe she isn't. Maybe she tried, but she just really wasn't happy with Clark, and didn't know how to end it in a better way. Can we know that? I don't know. But it's much more in character for Kent to see the good side of her, to understand and forgive her in order to move on, than to hate and disregard her as unworthy.
