(I also have a soft spot for parts of Picard season 1)
I actually like that this is a favorite episode thread, because season one of Picard has "Nepenthe," which I come back to again and again. I love how Troi is the central character of that episode and the primary mover of the whole plot. It's the crowning moment for any non-titular TNG character in all of Picard, and superior to anything in S3!
