Frank taking the fall for Debra when she tries to hide a family heirloom of Marie's because he considers her to be like a daughter to him. The fact it pissed off Marie was a bonus.
The series finale ends with Debra and Ray reconciling their differences with a simple, touching scene towards the end where they reiterate that they really do love each other.
In addition, Ray's near-death experience seemed to have the same effect on Robert, as Amy reveals that on the ride home from the hospital Robbie had to pull over for a while because he had tears in his eyes. Despite their sibling rivalry, he did genuinely love Ray.
Another good moment in the finale: When Ray discovers that he briefly had trouble waking up from the anesthesia, he wants to know how everyone reacted. When Debra protests that it was only thirty seconds, Ray retaliates with:
Ray: Thirty seconds is a long time! What went through your head? Thirty seconds, okay, go. I have to plan a funeral. I have to raise three kids myself. On the other hand I can start dating again. You know what? I'm gonna need new shoes. You know who's cute? Gianni. Marie: (appalled) Debra! Ray: So what? I mean, what? You didn't think of anything? Frank: HEY. I was there, and I saw your wife fall apart. I never saw her look like that, and I'll tell ya, I never want to see her look like that again! (Ray looks humbled)
There's another moment for Robert in the finale: when the doctor first comes out to tell the family that Ray's not waking up, he immediately steps forward and demands to go into the surgery room to try to help him—"I'll get him up. I'm his brother."
Ray helping a bed-ridden Robert (who was hit by a charging bull) put on a new upper thigh bandage in "Robert's Rodeo".
When Robert, Ray, and Frank are going to the horse racing track instead of going to therapy, there's this:
Ray: So granddad hit your dad, and your dad hit you, and... you never really hit us. Frank: I couldn't, you know. I was always weaker than him. Robert: Maybe you didn't want to be like him. Frank: I didn't.
In "Frank's Tribute", after a massive fight in bed during which Marie accuses Frank of not loving her and not having a single nice thing to say about her, Frank silently gets up and leaves the bedroom. Things look bleak for a moment, but then Frank returns and starts tenderly wiping Marie's beauty facial mask off.
Marie: Hey! Frank I need that! What're you—?
Frank: Shh. I love you better without that crap on your face.
One episode involves Ray dancing with Ally at a some school event and reminiscing about her birth. The whole episode can technically qualify as this trope, but particularly the bookend scenes in the present day that show Ray smiling wistfully at Ally and then agreeing to dance with her despite his insecurity about his dancing skills.
When the family stops arguing temporarily because they hear through the baby monitor Robert singing a song to the twins to calm them down.
Robert: Inchworm, inchworm, Measuring the marigolds, You and your arithmetic, You'll probably go far. Inchworm, inchworm, Measuring the marigolds, Seems to me you'd stop and see, How beautiful they are.
In "The Ball," Ray is upset when he learn that the signed Mickey Mantle baseball Frank got him is actually a fake, that Frank himself signed. When he confronts his father, Frank tells Ray that he tried everything, and he truly meant everything, he could to try and meet Mantle so he could sign the baseball, but things never worked out, and ultimately decided to sign it himself and give it to Ray because he didn't want to disappoint his son. At the very end Frank says he'll understand if he throws it away, but Ray, touched, simply replies, "You know... I think I'll keep it."
In "The Cult" Robert And Ray come up with a plan to get Marie and Debra talking again by faking an intervention, Robert says he's going back to "Inner Path" because he knows he can't find happiness with his family, Marie and Debra run after him, Robert asks why he should listen to them when they can't even talk to each other, Marie and Debra say they can and hug each other, finally ending their feud.
In "Pet Cemetery", Ally's hamster dies and Ray reluctantly agrees to hold a proper funeral. After hearing her heartfelt eulogy for the hamster, Ray gives his own speech, telling Ally how grown up and responsible she has become and how proud of her he is. Even Frank is affected by it:
A minor one, but after Ray blows up at his parents for never appreciating anything he gives them for Christmas, Marie and Frank do their best to hunt the present, an toaster with the Barone family's names engraved on it, down at the local store. Ray is incredibly happy once he finds out that they even got in trouble with the store's security while trying to get it back.
The last couple minutes of "The Contractor" showcase a very sweet chemistry between Ray and Debra that isn't seen in too many episodes.
Ray: He's (Gianni's) not my friend anymore. Debra: (sympathetic) Oh, I'm sorry Ray. Ray: No, I mean, it's just look, whatever. Debra: I'm sure you'll work it out with him. Ray: Yeah well, we'll see. Debra: I'm still your friend. Ray: ...You're a girl. (Debra smiles)
"Whose Side Are You On?": Even though she was goaded to do it by Ray, there's a sweet moment when Debra, who's been making bets with Ally and the twins about stupid things Ray does, actually builds him up:
Debra: We're actually not going to do betting anymore, because I think it's left you with the impression that Daddy's not so cool. And Daddy is cool. (kids have a confused look on their faces) No, he is! You know that. You know that, right? Listen, I just want you to understand that when were doing all that stuff, Iike betting on haircuts and the grocery store and "ls Daddy zipped up today?", listen, I want you to know that I think your daddy is a great guy. He works very hard, he has a lot of fun with you guys, and we're lucky to have him. I love Daddy very much. And you know what? I would rather be married to him than Superman. Michael: (can't believe his ears) You would? Debra: Yes, I would.
In "Baggage," Debra and Ray get into a passive-aggressive fight over which of them should carry a suitcase up to the bedroom. They have a battle of wills for weeks, and when Marie finds out about it, she does something surprisingly out of character. She invites Debra over to her house and tells her something she's never even told Ray and Robert: namely, how the giant, tacky fork and spoon that hang on the kitchen wall got there. It turns out they were a wedding present from a relative of Frank's; Marie wanted him to return them, but he wouldn't, and the two ended up arguing just as Ray and Debra did, with Marie remembering the whole unhappy incident every time she comes into the kitchen. She then tells Debra that fighting over something so trivial isn't worth it, and urges her to make up with Ray. It's one of the only times in the whole show that we see Marie offering Debra genuinely good-natured advice—there's nothing manipulative or pushy about the scene. It's just a mother-in-law trying to help her daughter.
In "Grandpa Steals," Ally sees Frank "sample" some cereal from the grocery store and get into a loud, angry fight with an employee over it. She becomes terrified and avoids Frank, which genuinely upsets him. He comes over and has a one-on-one talk with her, and you can tell he's trying his best to convince his granddaughter that he's not a scary guy. At her insistence, he goes back and apologizes to the employee, who still acts like a complete jerk. Frank is ready to fight again...but instead looks at Ally and quietly takes her hand as she smiles at him. Of course, as he walks out, he "accidentally" knocks over an entire display of oranges, capping the scene with a Crowning Moment of Funny.
Frank gets another one in "Debra at the Lodge." As the title suggests, Debra starts volunteering at Frank's lodge. The men pay her a good deal of attention, which she thinks is flattering—but it turns out that it's a far more "adult" kind of praise. Ray doesn't realize it until Frank tells him how upset he's become over it, but he can't say anything to his lodge brothers, because they're sworn to secrecy about what happens in the lodge. When Ray goes down and tries to sort the situation out, the other lodgers make fun of him—until Frank suddenly appears and tells everyone exactly how he's feeling. The brothers warn him that he risks being kicked out of the lodge, but Frank says Debra is worth it:
Frank: This is Debra! She's not just some cheap floozy! She's like my own daughter!
The genuine love between Ron Fernandez and his father showcased in "The Kicker" when Frank reluctantly gives the football back that he stole.
While the moment before it was tearjerking, in "Sister-In-Law" Amy immediately apologises for her harsh words towards Ray, and the two have a heartfelt discussion in private.
The end of "Marie's Meatballs" where we find out Marie was planning to leave Debra all her recipes in her will.
In "Tasteless Frank," Frank adds some salt to Marie's lasagna one night; this throws Marie into a horrible depression, as she claims that her cooking is all she has. Frank eventually tells Ray and Robert that he's lost his sense of taste because of a medicine he's been taking to ensure that he can remain potent in the bedroom. After the secret inevitably gets out, Marie, rather than getting upset, sincerely thanks her husband for thinking so much of their married life that he was willing to take medicine. And then it gets even sweeter:
Frank: Thanks. But if it's all the same to you...I'd rather have the food.
Marie: (crying tears of joy) Oh, Frank, that's what I want, too!
"A Date For Peter": Ray has a cocktail party at his house to set Peter up with a woman. At first, none of the women Ray invited excite Peter. Then Peter meets Peggy, Ray's arch nemesis, and the two hit it off immediately, discussing sci-fi and comic books. Ray purposefully meddles in Peter and Peggy's conversation, because he doesn't want Peter to date his sworn enemy. At first, it looks like a Downer Ending, as Peggy walks out on Peter ("You know what? It was really nice to meet you, but I came here for a drink, not an arranged marriage."). But then when Ray goes to Peter's apartment the next morning to apologize, Peggy exits Peter's bedroom dressed in only a T-shirt and kicks Ray out. It's a nice unexpectedly happy ending for Peter.
Peter: Oooh, Princess Leia! (the two go back to the bedroom)
