Ron's part:
Here I am, face to face, with a situation I never thought I'd ever see.
Strange, how a dress, can make a mess, to make her nothing less then beautiful to me!
It seems like my eyes have been transfigured...
Something deep inside has changed!
--- And open wide and hold that trigger.
This could mean....DANGER!
Falling in love, falling in love, falling in love...
I have fallen in love, fallen in love, fallen in love...
With Hermione Granger.
(and I really think that was in act 2, like, I'm positive.
And the dancing scene, where Draco rolls and stops Ron from talking to Hermione, I was laughing so hard, and Zefron? Ohhhh god.)
Draco's Part:
What?! What the hell is this!? You expect me to sing about her? I don't care, about her...
It's just a...little makeup. Draco, wake up! I'm mistaken...
She...is the HOTTEST girl I've ever seen!
Now, 'cuz she's like I girl I've never seen!
Don't know why I've ever been so mean...
This could mean...DANGER.
I'm falling in love, falling in love, falling in love...
I could be I'm falling in love, falling in love, falling in love...
With Hermione Granger.
