Sirius and James had been best friends since the first day of Hogwarts and nothing had ever come between them, that was till one of them decided to grow up…
James was with Lily.
No defying any fact of their loving relationship, that's the way it was, and Sirius hated every damn bit of it. It was never James and Sirius any more, it was James, Lily and Sirius, he was envious of his best friends girlfriend. Sirius tried to make life with himself as difficult as he could when he was with Lily. He would make awkward decisions or take a long time in making a decision about James for her, or he would sometimes ignore her completely. To him, Lily was the very person that would take away his best friend, he didn't want that, he couldn't stand it and especially now that she is part of their 'group' he can't contain his hatred and jealousy of her any longer.
Though when a potion goes awry a change of heart and soul just might convince Sirius that James is meant to be with Lily…
'James, I'm just saying that this is going too far! I mean letting her in on the potion? If your doing this then why can't I tell Rose?' Sirius ranted, for about half an hour he had been yelling at the top of his lungs in the boys' bathroom about how Lily should never have been told about their animagus abilities.
'Because….' James shouted, trying to equally calm down his best friend 'Lily's different,'
'How's she different, James? How?' Sirius demanded.
'Because I love her! You have never loved any girl you have ever dated!' James called
'So?'
'So? I think that's the clear point right there Padfoot?' James said angrily
'Just because I'm not ready to forget about my friends and think about a wife and kids doesn't mean I have never loved Rose!' Sirius then lowered his voice to an almost audible whisper 'James you're barely 17 and you're acting like Lily is the one,'
'And if she is?' James said indignantly
'You're seventeen!' Sirius up roared 'you've got more important things to think about than love and poetry! You're training to be an Auror!'
'I can't believe you're my best friend, 'cos at the minute you're treating me like your worst enemy, I love Lily, she doesn't change anything between us-'
'She obviously has,' Sirius said spitefully
'Hey,' James said defendingly 'that's out of order,'
'That's out of order?' Sirius said incredulously 'If that's out of order then tell me, Prongs, how is inviting Lily to become animagus in our "secret" and I say again "secret" group, in order??'
'She will help Remus more than any of us, Padfoot, if you are truly my best friend then why won't you accept Lily?' James said.
'Because she's changed you James, she always had an effect on you! I just never believed you'd take a girl serious, not like this. You've changed, its like, its like you've turned into your father,'
Silence rang around the room, it was as deafening as a pin drop amplified. Sirius made to leave the room and James stopped him with a swift movement of his hand.
'We're not finished, I am not like my father and I never will be,' James said in an almost deadening whisper, he let Sirius go and heard the door of the bathroom slam with an almighty force.
'Padfoot, is everything all right? Lils, shes up in the dorm room crying her eyes out about you,' Lupin said hurriedly, clutching his side as though he'd been running a race.
'Do I look like I care about Lily fucking Evans, Moony?' and Sirius stormed of, thundering down the halls of Hogwarts, he found that his feet carried him outside to the grounds of Hogwarts.
