- When Marty first meets with "Citizen Brown Universe" Biff in Episode 3, you find out that Biff is forced to be a good guy and follow all the rules or else. At first, you don't seem sorry for him as now he's not the evil bastard he was like in the past movies and previous episodes, looking to be a changed person for good. But you can tell that he regrets dearly being a Citizen Plus by the way he talks, especially when he gets to the part about giving up his many dogs, you can't help but feel sorry for him.
- A minor example comes in "Citizen Brown", with (as Marty looks on from below) the DeLorean falling out of the billboard and smashing into the ground. While not as bad as seeing it get crushed by the train in Part III, it's still a smack to the face to see the DeLorean get wrecked... again.
- In Episode 3 it's hard to watch Citizen Brown struggle with what he's done. The road to Hell is paved with good intentions, indeed. Thank God for Doc's notebook...
- Also in Episode 3: When you finally manage to get Citizen Brown to believe that you're from an alternate timeline, what is the very first thing he asks? "In this... other world, the one you say you come from... am I... am I... happy there?" And he has this desperate look on his face.
- Citizen Brown aka Doc!A's FaceHeel Turn as he doesn't want Edna to become a Crazy Cat Lady is very sad for Marty, as well for the player. Can be a What the Hell, Player? as well.
- After Marty breaks up Emmett and Edna, Emmett hides up on the clock tower ledge, and sings a couple lines from Trixie's "I Don't Care" to himself.
- In addition to that, Marty is trying to cheer up Emmett about listing things Emmett cares about. Marty lists himself and slips up by calling Emmett the name Doc. Emmett responds by telling Marty that he loathes him for ruining his life. Marty feels guilty, and while Emmett doesn't know who Marty truly is, it is sad and jarring to hear those words from Doc to Marty.
- Episode 5: Citizen Brown!Doc being erased from existence as Marty is kneeling next to him.
- Episode 5: Having to see the completely rusted and dead DeLorean in Alternate!1931. Its one thing to have to see the car, a staple, a character, an icon, of this franchise get trashed in BTTF3, but to see it rust off into a wreck, a hollow, decayed and empty shell of its former self, its parts stripped, to make a clunky and rudimentary alarm system, is a real punch in the guts. Imagine encountering the long decayed web-covered skeleton of Bugs Bunny, or Mickey Mouse. Even Marty says, half-choked, "I hate seeing it like this". If Doc's talked to while looking at it, he'll just quietly ask Marty to not speak.
