In another deleted scene, Linnie finds that Peter is unable to sleep since he too is worried about Kevin. They then share a heartfelt moment on why they both think togetherness is so important at Christmastime.
Home Alone 2
Buzz's heartfelt speech/apology to Kevin. He's actually kind of a nice kid, when not acting like a total dick.
The first and second time we hear "Christmas Star". The first showing Kevin missing his family once again while looking at a view of New York at night. What adds to the heartwarming is that he says goodnight to his mother, while at the same time in the Florida Resort Kate is saying goodnight to Kevin. The second time was before he decides to deal with Harry and Marv. He makes a stop at the Beth Israel Hospital Children's wing. A sick kid looking out the window and waving to Kevin who waves back. This provides his incentive to stop Harry and Marv from robbing the toy store since the proceeds are supposed to go the the hospital.
Buzz giving Kevin the first present to open on Christmas morning.
Uncle Frank cheering for Kevin shortly afterward. Nice to see after he spent the first two movies being a complete ass to him.
Kevin thanking the Pigeon Lady for saving his life, followed by the lady blowing a kiss to him.
Kevin giving the second turtledove ornament to the Pigeon Lady.
Kevin's relationship with the Pigeon Lady is this, being he convinces her to not be so closed up, telling her that you're going to be hurt sooner or later, but shows you're alive. Especially heartwarming in the end when he gives her a turtle dove and says they'll be friends forever. Daaaw.
Harry's promise to take Marv to the Central Park Zoo when they have time to kill before the heist. Nice to see him doing something nice for what we might assume is his only friend.
Home Alone 3
Alex getting rewarded for his role in catching the gang, as well as getting respect from his family for it (in contrast to Kevin's, who didn't know about Harry and Marv), who don't even seem to care too much about any of the damage his traps caused to the house (no doubt because of said reward).
