Hawkeye, despite disliking Hank Pym, decides to help him find Wasp because he knows how it is to lose a family member. The moment is genuinely touching, in contrast to its horrible conclusion.
Another touching moment is when Wolverine hugs Kitty Pryde, telling her that if they're going to start over again, they'll need people like her.
Instead of going after Magneto, Spider-Man spent the entire night diving again and again to save innocents. It's considered such an iconic moment of Ultimate Spider-Man that it's the reason JJ Jameson pulls his Heel–Face Turn.
