"Guys Like Potter" will make you want to hug Snape, no question.
Soon after "Those Voices," Snape looks into the Mirror of Erised and sees Lily. He looks at her for a second, and then silently exits the stage in order to protect Harry and the others. Lily is left alone, and the lights fade to black...
From A Very Potter Senior Year
"I Was" is quite depressing, capturing both Harry and Tom Riddle's sadness regarding being unwanted and Harry's nostalgia for his old adventures.
"Everything Ends". The title alone kind of explains why.
Harry saying a final good-bye to Hogwarts while addressing the audience. Becomes a meta Tear Jerker when considering it as Darren Criss saying good-bye to his first superstar role and (at least temporarily) the StarKid fandom in general.
"That was for us and I donít think that anyone there will ever forget it, because Darren will always be in Star Kid, but things are changing from here on out and he will never be our Harry again.."
"It's all that I loved, and all that you'll see..."
"OK is wonderful."
"Things come and go. Nothing lasts forever, kid." and "You know, there's two things in this world I love. One of them's you." Fucking hell.
Quirell and Voldemort's speech about Harry Potter, how it's brought them joy, family and love but sometimes you need to let things go.
"Harry, Hermione's Petrified, and I can't do anything to help her!" Joey Richter's delivery is incredible.
Several of the actors are visibly tearing up during the last couple scenes. Several people have stated Lauren Lopez in particular got them crying too.
All of the other characters lining up to hug Harry goodbye, especially as most of the actors are genuinely crying. Special mention goes to Neville's goodbye—while the other farewells are softened by the overall ridiculousness of each character, Neville just gives a quiet, understated, "Goodbye, Mr. Potter," and presses his face into Harry's shoulder during their hug. The whole thing is clearly just as emotional for the actors as it is for the characters.
