I've just watched the first 20 episodes (2 to go) of Season 11.
Episodes 16 & 17 were of Joanie finally getting married. The wedding reception seemed a closure to the series.
Then episodes 18 - 20 (& probably the last 2) we have Joanie, again, but single and dating others.
Were these listed out of order of actual airing?
