Pitiful creature of darkness, what kind of life have you known?
God grant me courage to show you - you are not alone!
Sierra Boggess' Christine cranks it up to eleven: she kisses him, hard, then pulls away, looks him right in the eyes - and goes back for more. There's no way he can deny she's doing it of her own free will after that. You can see Karimloo's Phantom melting into her arms on that second kiss, going from disbelief to pure passion.
"Christine, I love you." Both times.
Christine: Say you love m—
Raoul: You know I do.
The whole rooftop scene is one for Raoul. At this point he doesn't think the Phantom is real, but seeing Christine so utterly broken makes him realize that her fear of him is - "All I Ask of You" is all about how he takes that fear seriously and wants her to feel safe again.
At the end, the Phantom has finally let Christine go, and the mob is descending upon his lair. He plays the monkey musical box and sings a few lines from "Masquerade", before sitting down on his throne, pulling a blanket over him and disappearing forever (or at least until Love Never Dies). A Tear Jerker of an ending that will have everyone feeling for the Phantom, at least a little.
Right after the Point of No Return. The Phantom is no longer playing games, or pretending to be Christine's Angel, or tempting her - he is actually pleading for Christine's affection. The vulnerability of such a powerful character, as well as how crushing his loneliness was, was in itself nearly a Tear Jerker.
Erik: Say you'll share with me one love, one lifetime. Lead me, save me from my solitude. Say you want me with you, here, beside you. Anywhere you go, let me go too! Christine, that's all I ask of -
Meg going looking for Christine after "Think of Me" to congratulate her is simple but sweet, as is the fact that throughout the show she never feels anything but genuine, tender pride towards Christine's success. Of all of the characters in Phantom, Meg retains the most honest, innocent outlook through everything that happens; her first instinct is always to comfort and care for Christine, never of revenge. In several ensemble pieces, when even Raoul is obsessing over outsmarting the Phantom little Meg Giry is the only one who never thinks of anything but Christine's happiness and safety. She's a walking Heartwarming Moment.
... Come to think of this, more or less all of these Heartwarming Moments requires a rejection of LND...
The end of the 25th Anniversary Celebration at the Royal Albert Hall, in which all the West End Phantoms from the past twenty-five years join and sing "Music of the Night". Although Michael Crawford was onstage, he did not sing with them, because he had just gotten back from playing the Wizard during a matinee show of Andrew Lloyd Webber's The Wizard of Oz. (You can see him at least mouthing along when the whole cast is singing together, however.)
Crawford did get his own Heartwarming Moment at the end, though, when Ramin Karimloo (who performed the Phantom in the concert) bowed respectfully to him at the show's conclusion, singing, "You alone can make our song take flight!" in tribute.
Crawford was not the only one moved to tears in that moment.
Definitely not the only one.
Besides the multi-Phantom goodness, there was also the interaction between the three leads at final bows. Ramin reaches for Sierra's hand and kisses it, then grabs Hadley's hand with the biggest grin (it does help that they're best friends in real life).
Even cuter is the very ending, when Ramin scoops up Sierra and carries her offstage after the celebration ends.
And Sierra tried to pick Ramin up first! So cute!!!
It speaks volumes to Ramin's humility and Colm Wilkinson's general awesomeness that, after the group bows, Colm grabs Ramin by the arm and leads him to the front of the stage for another bow.
Hadley Fraser's adorable laugh as he spins Sierra around after All I Ask of You, and just the sheer level of happiness in their expressions.
At the final curtain call for Hugh Panaro, one of the longest running Broadway Phantoms, his beloved dog Soot was brought out onto the stage and lifted up to give a wave to the audience.
In the movie musical, Madame Giry brushes Meg's hair a little bit as they watch Christine sing "Think of Me", silently assuring her that someday she'll be a star, too.
Let's face it. Even though Erik is sympathetic and we love him, Christine would be 100% justified in hating his guts — after everything he did to her and her loved ones, it'd be a perfectly reasonable and understandable reaction. But... she doesn't. In spite of all he's done, all he's said, she still manages to feel genuine compassion and pity for him.
