Winx Club/Heartwarming

• The way Layla earns her Enchantix. Valtor has blinded Layla, so Queen Ligea promises to heal Layla's eyesight with her scepter (after the Winx and her daughter rescue her). A little later on, Queen Ligea is gravely injured, but there's not enough sunlight for the scepter to heal both Layla's eyesight and the queen's health. Ligea's daughter tells Layla to use the scepter to heal her eyesight, as her mother promised her, but Layla instead chooses to heal the queen.
• In Episode 25 of Season 4, when Morgana reveals that she is Roxy's mother. After Roxy releases her from the mirror, the two embrace each other.

Roxy: Mom, I thought you were-- Morgana: Shh. Don't say it.

• At the end of Secret of the Lost Kingdom, when Bloom frees and finally reunites with her birth parents, Oritel and Miriam. She, her parents and Dafne/Daphne share a group hug.
• One from Episode 3x12, where Flora earns her Enchantix. After she dives in after Rose/Miele, she sees Rose about to be entangled in some seaweed. Flora manages to catch her and places her in an air bubble to bring her back to the surface. Just before she places Miele in the bubble, she tells her, "I love you, my little blossom." The line implies that she knows she's about to die, but only very slightly (it could also be the river's poison in addition to the seaweed entangling her). Now, someone tell me: Why did 4kids change this line?!
• In Episode 25 of Season 1. Flora is attempting again to change Mirta back into her human self. Musa and Stella are ready to give up, but Flora refuses and in one last attempt, she finally manages to change Mirta back! Just before Mirta changes back, she has a vision of her and Flora reaching out to each other and after she is back to her human self, she and Flora embrace each other.
• The finale of Season 2. Bloom has been forced to turn evil by Darkar and the Winx and specialists have gone to rescue her. Near the end, just when Bloom is about to defeat them, Sky breaks the evil spell over Bloom by confessing his love for her.
• The end of Episode 15 of Season 2. Musa performs a concert at Red Fountain, despite that her father had threatened to pull her out of Alfea if she does. The reason for this is Musa's mother died from illness when she was a child and the family couldn't afford medicine due to being poor musicians with music as their only source of income (he didn't want to see Musa in this position). At the end of the episode, Musa and her father make up about the argument they had earlier and a picture of Musa's mother appears above them.
• The moments between the Winx and the Specialists in episode 2x25 just before the Winx go off to rescue Bloom. Especially the moment between Riven and Musa:

Musa: I guess you're above all that mushy stuff, right Riven? You don't need anybody? Yeah, so anyway... (Begins to walk away, only for Riven to suddenly grab her arm and hug her) Riven: Do me a favour. I just wanna hear you say that you'll come back. That you'll come back, to me.

• • Thankfully, 4kids did not ruin that scene and it's just as heartwarming in their version.
• YMMV on this one, but episode 2x23, when Flora finally confesses her love for Helia (with some help from Chatta).
• When Tecna is finally found in the Omega dimension (Bloom is the one who finds her).
• This moment from one of the Winx in Concert videos. Basically, the video was about Layla and Nabu going against Icy and Valtor in an ice skating contest with L/N winning. And Layla, seeing how upset Icy is over losing, takes one of the flowers thrown at her and Nabu and offers it to Icy. Aww.
