Just Let It Be
I understand people's frustration and reasoning for why some of the stuff that happens in the Final Episode doesn't make sense, but with that said, I think it would be best for us to just not overthink it too much because it's just gonna make your heads hurt. The less you think about it the more you'll enjoy the episode. Again, I understand that a lot of people on here have issues with the episode, but it really doesn't matter at this point. The Final Season is over, so just let it be.
