* Fits of these with the ending and a certain scene involving a collapsing bridge before the final Colossus.
** After following you silently yet with utter devotion, your only companion in the vast empty world is lost. And to top it off, it was to save ''your'' bacon...
* Here's an experiment. Try to look the Colossi in the eye before you kill them, then watch their slowmo deaths.
* The DownerEnding, [[spoiler:as you try hopelessly to fight against the current and see if the girl you killed sixteen colossi for is okay. Then you shed tears of joy when she wakes up to find your loyal horse who's NotQuiteDead, and then as the credits roll, the camera pans over the decaying carcasses of all the Colossi.]] So simplistic and honest, it's overwhelming.
** What's even worse about the ending is that [[spoiler: while ''you'' know that Mono's okay, Wander doesn't, since he's killed before she wakes up. He probably died thinking he'd failed her and that everything he did was for nothing.]]
** YMMV, of course. There are all sorts of interpretations to this game. [[spoiler:Wander sprouts horns near the end, and then turns into a Colossus, but it's implied that he may be able to someday atone for his sins. This may stretch believability in terms of how quickly it could happen, but at the end, Mono finds a baby with horns who ''could'' be Wander!]] So you could be crying tears of joy. Maybe.
* Wander's pained face and outstretched arm towards Mono after [[spoiler:one of the guards pierces him through the chest with their sword.]] He's either losing his own sense of self or dying, yet all he apparently wants to do is touch her.
* The scene where Wander dreams about Mono coming back to life. Ten times more wibbling when he actually mumbles her name before waking up.
* When you get to the end and fully realize that [[spoiler:Wander, and by extension, the player]] is the real villain in this story!
** When Lord Emon [[spoiler:(who, from a certain perspective, is the villain)]] actually ''won''.
* Killing [[GentleGiant Phalanx]] is something of a traumatic experience, mainly because it never does anything to attack Wander, ''ever'', even when he starts firing arrows at it and stabbing its weak spots.
** It can happen first with Avion. One thing is to defeat a foe that starts attacking as soon as you are in sight, but Avion starts attacking only after YOU attack him first. The moment you see him crashing into the water there is a high chance you'll begin to seriously ask yourself "What have I done?"
