'Evans!'

'What are you doing here, Potter? This is a rehearsal for Prefects only.'

'Moony's sick. I bravely volunteered to fill his dancing shoes, for the sake of Gryffindor.'

'For Gryffindor. Of course.'

'I couldn't leave one half of the team under-practised could I? The Valentines Ball needs this, Lily. It is a necessary, chivalrous thing I am doing. Besides, I'm a much better teacher than Lupin anyway.'

'Eurgh! Fine. For Gryffindor. But just because I'm dancing with you doesn't mean I like you. I hate you, Potter. Just so we're clear.'

'You say hate, I say unresolved sexual tension. But hey! Whatever floats your boat, my dear.'

'I never thought I'd be glad to dance with you Potter, and I was right.'

'You can deny it all you want but dancing like this is definitely a form of floor play.'

'Ha, ha, ha. You should toss out more of those oh-so-witty remarks more often.'

'Really?'

'Yes - that's all they're good for.'

'Ouch Evans. I was joking.'

'It wasn't funny.'

'You're right. It was hilarious.'

…

'Hey, Amos!'

'Evans, what are you doing? For Gryffindor, remember? Not red and yellow crossbreeds. Will you please think of the children?'

'I'm switching partners. Deal with it or not.'

'I choose not. Eyes off, Diggory. Merlin, Lil, you really need to smile sometimes. It's the second best thing you can do with your mouth, after all.'

'Something incredible you could do with yours is shut it.'

'Just keep dancing, Evans. McGonagalls watching us now. That's what I appreciate about Minny, she thinks of the children. No Gryffin-puffs around her, that's for sure.'

'... So that's it? "Keep dancing Evans"? You're not even going to apologise?'

'For what, exactly? I didn't do anything wrong, Lily.'

'Oh, I'm so sorry. I forgot I was talking to the James Potter. Must've slipped my mind that you can do or say anything you want and nobody can object because you're just so amazing and talented and handsome and never do anything wrong. No need to apologise, it was my mistake.'

'Careful Evans. Those are your words, not mine.'

'Eurgh! You know, Potter, acting like a dick won't make yours any bigger. You're repulsive.'

'Mmm, you take my breath away.'

'I'm just suffocated by your bullshit.'

'I'm beginning to think it's better to lose a lover than to love a loser. I'm doing you a favour here, and all you can do is yell at me? I'm getting pretty tired of it Lily.'

'And I'm getting Deja-Moo.'

'What?'

'I've heard this bull before.'

'Argh! You may not like my personality, Evans, but at least I have one. All you are is a stick in the mud bloody prude who hates fun. You never even gave me a chance! I was just trying to make you laugh. I don't know why I bothered.'

'I wish you wouldn't.'

'Enough people hate you already, Evans, stop working so hard to get another.'

'Yeah? Well I. hate. you.'

'Good! I hate you too!'

'I won't dance with you again, Potter.'

'I never wanted to in the first place! I did it for Moony.'

'Fine.'

'Fine.'

…

'Where are you going? Evans? EVANS! OI!'

Maybe it's just me, but I so see Lily as the bitter type early on. To me, she'd fight tooth and nail to not be super romantic about V-day because she prides herself in realism. I think James was right though - her hatred is just unresolved sexual tension ;) I'm calling it Never (dance with you again), okay? N is a hard word! Work with me here!
