The whole episode is just nonesense.
They are talking and talking and talking withoht actually bringing the plot forward. The whole idea of wanting to rescue that one character is a jokingly bad undertaking. Everyone one the way acts super stupid. And then, there is no payoff.
The ending sequence was just plain ridiculous. I mean... It was all there to end it. Yet the character is super dull. I just can't understand how such a bad script can get greenlit. Is there even an authority checking for the scripts on the whole show? It seriously doesn't look like. And there we are now, after 5 episodes into the series finale and there is really not much that happened and could've not been squeezed into two episodes.
