Everyone on the Enterprise is such a dick to Worf. They throw him a birthday party even though they know it will make him uncomfortable and sing Happy Birthday to him in poorly-translated Klingon. They give him a bunch of crap presents because, lol, wouldn’t it be funny to give Worf a painting, yeah yeah do it Data. And the whole time they’re laughing at his attempts to politely deal with it.
And then his son sends him a genuinely thoughtful gift, a cast of his forehead ridges, and Worf is genuinely delighted for a moment! But no time for that, time for more painting jokes, lol lol lol
This is actually one of my top 5, maybe even top 3, favorite episodes of TNG. Michael Dorn does such an incredible job showing just how difficult Worf finds it to live amongst other species, with no other Klingons around.
The shifts from one reality to the next were subtle and yet distinct, and then you have LocutusWins!Riker and his terrified desperation.
But oh did my heart ache for Deanna once she realized that Worf had never courted her, never married her…
