You know, just a few short months ago no one would have been able to answer your question here and you would have been directed to the Spoiler forum. *Sigh* - the good ol' days.But... (and I almost hate to ruin the outcome for you) she does come back. I haven't been watching the reruns so I'm thinking you're talking about when she gets sent home for 30 days to try to get things together.
I won't ruin it for you after that. You have not heard the last of Spit-up Lisa. Or haaaaave you? *wink*

God is good all the time and all the time, God is good.
