A Disclaimer: I do not own Harry Potter. Or 'The Whacky Adventures of Severus and His Dog Winnie'

Severus Snape entered the headmaster's office with the customary billowing of his cloak and sneer in place.
'Seveus!' the man with infernal twinkling eyes exclaimed. 'I have good news.'
Snape fought the urge to roll his eyes. This so called 'good news' was probably the finding of a new supplier of lemon drops.
'Lord Voldemort has been vanquished.'
Snape opened his mouth to retort scathingly, but the words never quite reached his mouth as he gaped at the beaming wizened wizard before him. Snape shut his mouth with a sharp clack of teeth on teeth and sought to find his bearings.
'Yes,' the fool continued, utterly oblivious to the reaction his words had just caused. 'The prophecy was fulfilled, Severus old boy. By Jeremy Potter no less.'
Snape didn't bother to shut his mouth. The man was obviously senile.
'Yes, yes, there'll be here in a minute,' Dumbledore said, absently fiddling with one of many silver contraptions as he glanced towards the open fireplace.
As if his words had been a signalthe flickering orange flames flashed green and the figure of Lily Potter appeared, clutching a black haired, green eyed boy to her breast, followed closely by the 'arrogant prick,' James Potter, also holding a small child. This one had flaming red hair and hazel eyes, and was the complete opposite of the quiet boy held by Lily as he proceeded to bawl his eyes out.
Snape's lip curled in disgust and he turned his attention back to Dumbledore, who's eyes were twinkling at an inhuman pace.
'Welcome,' he began jovially, standing to greet the Potters and ushering them into comfortable leather armchairs he'd just conjured. 'I was just telling Severus here of Jeremy's remarkable achievement.'
He motioned towards the red haired boy and Snape did a double take. Surely he was not serious. How exactly the ginger crybaby could have defeated Lord Voldemort was beyond even the wildest imaginations. Looking at them closely Snape noted that each had a particularly prominant scar in the vicinity of their forehead. The green eyed boy's was in the shape of a lightning bolt, just over his left eyebrow, while Jeremy's was a ragged gash that ran past his right eye and tapered off just over his cheek bone. It looked more as though someone had run a piece of broken glass across his face than the mark of the most powerful dark curse ever created, as Dumbledore was now telling a barely listening Snape. The other boy's scar though reeked of dark magic, it was drowning in it, it seemed to cling in a dark cloud over the ugly lightning bolt scar.
'… And so Jeremy Potter is The-Boy-Who-Lived.'
'What!' Snape shouted before he could stop himself.
Dumbledore quickly adopted an expression of polite bemusement. 'Yes, Severus?'
'You can't be serious.'
'Serious, Severus? About what?' Albus was now looking suitably puzzled.
That Jeremy Potter defeated the Dark Lord,' Snape said slowly, drawing out each word. 'On what evidence do you base this claim?'
Dumbledore looked startled. 'Why Severus, surely the evidence is incontrovertible.'
Severus raised an eyebrow. 'Pray tell me,' he drawled. 'How exactly is this evidence so, how did you say it, incontrovertible?'
Dumbledore waved a hand absently in dismissal. 'Now, now Severus. Now is really not the time to delve into the wherefores and howsos. No …' He trailed off, looking at Jeremy with a fond expression.
Snape could only gape. The so called 'greatest wizard of the age' was making decisions based on mere speculation. 'But surely,' he tried. 'There must be some indication.'
'All the signs point to Jeremy,' Albus said with finality.
Snape tried one last time. 'But,' he said hesitantly. 'Isn't there a chance, a small chance, that you may be wrong.'
Dumbledore looked at him incredulously. 'Wrong? Severus, this is the greatest day in Wizarding history. Of course I'm not wrong.'
Snape bowed his head in defeat. This was going to come back to bite them, if his name wasn't Severus Snape.
