She was not very vocal about one episode. She just said that’s all she can promise ATM. I personally think we’ll see her towards the end of the season and definitely in the series finale. JMO has always come back for the shows final season.
She’s only agreeing to the premiere so far because it’s immediately after her play. She can’t promise anything else because she does not know what her schedule will look like. And making plans to be in the finale or close to end of the season which is a long ways a way now is silly.
