Thanks all!

Yes, I agree that "The Show Must Go On." Recasting Kate wasn't the issue that was bothering me. I'm truly happy to have her return.

What gave me pause was the completely serious suggestion of "Well, just lie and say that she was here!"

My cast members looked at me like I was crazy for not being willing to give such a casual lie.

That's what I'm contemplating. Has lying become so commonplace? Does a person's word no longer count for anything? Or do I just have the Stick of Self-Righteousness shoved too far up my kilt?
