Ahhh, well, it was the end of that episode where she essentially takes off, although we don't know it for sure until the next ep where she's gone, but everyone keeps calling her for advice.

Did you by any chance catch who played the charity lady/daughter? She looked familiar, but IMDb doesn't have much about this ep yet.

It's plaid! She's wearing it over something else, and she's not really a plaid person.

I don't know. They must be doing at least small bits with her throughout the season, because Tim tweeted photos of himself and Beth with Gina yesterday. (Today's the last day of filming for S2.)
