Then it all ends with Gray's monologue, clobbering you over the head with the central message if you somehow missed the subtext - there is only one right way to do being a person, and that's to be open and emotionally available.
This may be right in real life, but it's not what I want to see on the screen. I wonder what these writers would do with a character like Worf, Odo, or O'Brien sometimes.
Keep clobbering Discovery! Much like the half-black, half-white aliens we are nowhere near to learning the lessons, sad as it may be.
