[[caption-width-right:350:“I never knew my dad could be my best friend.”]]
* The FridgeBrilliance that sets in after Bowler Hat Guy reveals that Cornelius Robinson, this brilliant, successful, world-famous inventor/industrialist/patriarch of the amazing and loving Robinson family, is ''Lewis' future self''. You realize: Oh my, ''this'' is Lewis' future if he doesn't give up, and what's even better, he ''builds it himself''. {{Anvilicious}} as it is, it ''works''.
** Seeing the family he's built makes it even stronger. Here's a man who has had a lot of people care about him but never really had someone to call his own family. Once he's found success, what does he do with it? He invites all his extended family to live with him, and in the end, this is what he is more proud of than anything he's ever invented. It's very clear he's as happy to be with them as they're happy to be with him.
* The ending montage, complete with a perfect song to finish a good movie. [[https://www.youtube.com/watch?v=2MCdfZCftkI Just watch it.]]

These small hours still remain\\
All of my regret will wash away somehow\\
But I cannot forget the way I feel right now...]]''
* Cornelius showing Lewis around his lab and pointing out his favorite invention, the same one Lewis entered in the science fair and which won him his new family. Tom Selleck nails it to the wall.
* The final scene with Wilbur. He finally fills his end of the bargain and takes Lewis to see his biological mother from the night she left him at the orphanage, even if it means that he'll be risking his existence again.
--> '''Wilbur''': I never knew my dad could be my best friend.
** Also, Lewis' response to Wilbur's question, "Why did you just let her go?"
-->'''Lewis''': Because...I already ''have'' a family.
** The fact that Wilbur, despite likely knowing how much of a risk it posed (and probably being utterly terrified of what would happen if it went wrong), [[IGaveMyWord ultimately kept his promise]]. Flawed he may be but Wilbur is a ''great'' kid.
** When we see Lewis' birth mother is leaving him at the orphanage, she gives her infant son a big hug goodbye, knowing she'd never see him again. He sees this, knowing his birth mother truly did love him and wanted him to have a good life, leaving him at the orphanage knowing she couldn't make that happen for him.
** Even better, he witnesses the moment Mildred took him in. It gives the sense that although his goal in life is to find a family to adopt, Mildred has always been like a mother to him from the very start.
* Goob receiving some comfort from his baseball team coach after he fumbled the final catch of the game. Unlike his original timeline, it seems like Goob would have gone down a path where he wouldn’t have been consumed by hate for Lewis and had a better life.
* The Robinsons dropping everything and risking their lives to save Lewis from a dinosaur attack--Franny really meant it when she said they were all family there, even the kid everyone just met.
* Wilbur watching Lewis present the Memory Scanner at the science fair. He actually saw his father show off his greatest invention for himself. The proud smile on his face says it all.
* Lewis saying goodbye to the Robinsons...for now.
** A small one, but it's touching to see how Bud and Lucille get to see their adoptive son who is set to return on the day they meet him. Lucille looks like she's about to cry, probably thinking about how it was their best day as a family.
* The ending quote, revealing the origin of the ArcWords.
-->Around here, however, we don't look backwards for very long. We '''keep moving forward''', opening up new doors and doing new things, because we're curious... and curiosity keeps leading us down new paths. -- Creator/WaltDisney
* The Robinson Family. They aren't just pure awesome...they're pure heartwarming. One particularly touching moment is when Lewis' attempt at fixing the peanut butter and jelly device results in it exploding. Lewis is plainly terrified that the family will be upset (like the couple earlier in the film) and starts to stammer out apologies frantically. To his obvious surprise, they start congratulating him on a wonderful failure ([[MyFriendsAndZoidberg well, except Petunia]]) and Billie passes on the excellent [[AnAesop aesop]] of "From failure, you learn. From success...not so much."
* During his second attempt to use the Memory Scanner, Lewis asks his volunteer, who later turns out to be Grandma Lucille, for a memory to input. She goes through several possibilities, including winning a medal for the luge, and then finally selects one...her wedding day with Grandpa Bud.
* The fact that, as he knows it works, Cornelius ''encourages his future wife to be the crazy singing frog lady'' despite people thinking she's probably mad...
** And the fact that the frogs have their own little clothes, tiny instruments, and even a frog-sized bar with specialty fly vending machine...Cornelius really supports his wife's dream, and the frogs get to be like a part of the family too.
* A minor one, but when the Bowler Hat Guy ponders how to lure Lewis out of the Robinson house, he at first contemplates blowing it up, but he rejects this idea, seemingly not having the heart to kill Lewis, his former friend.
* After beating Tiny the T-Rex and freeing him from Mini-Doris, Franny runs up to Wilbur(who was almost eaten)and hugs him tight, peppering his cheeks with kisses. She also manages to comfort Lewis after he calls her "Mom" in his excitement over the fight, hugging him and saying it's okay when he sees she has a bruise from the fight.
* Lewis hugging Mildred goodbye. It's clear his ParentalSubstitute still means a lot to him. And then he leans out of the window as he, Lucille and Bud are driving away and waves goodbye to her.
* During a montage where we see various parents interview for Lewis but he's a no-show, focusing more on his invention, we see that the parents who interviewed him earlier are among those, showing that although the previous interview didn't turn out good, they were willing to give Lewis another chance.
* Lewis dropping everything and running to Goob's game to wake him up so he can make the catch. During his time traveling adventures, he saw how badly this loss affected his roommate and realized he [[InnocentlyInsensitive had accidentally caused it]], and he immediately puts his own problem on hold to fix it.
** Just as Lewis is leaving the orphanage after his adoption, he stops to bid Goob goodbye. Not only is the latter much happier, but he's in the middle of an adoption interview of his own, with his baseball trophy at his side. The interview looks to be going great, and Goob's future looks as bright as Lewis'.
* It may not be immediately obvious, but the fact that Lewis was not only adopted, but adopted by two accomplished scientists. He was adopted by parents who understood him and would nurture his gifts. Compared to the couple we saw in the adoption interview at the beginning of the film who would've been an obvious mismatch, given that his interests didn't line up with theirs at all. But he ended up finding parents who were perfect for him.
