A title for the season finale has been listed over on "When is it on". They don't have a non-generic synopsis yet, but it looks like "The Ending of the End" is most likely what it will be called.
And following that two parter, one final episode called "The Last Problem"
This site has used old titles before, so it could change. For now, this is what we have.
I'm sure we will get more information soon. Or the entire thing will release early on the moon or something. Who knows at this point.
Thanks to Robert for the heads up.
