Everybody Gets Twitterpated in the Springtime.
The first she finds out the three boys are Animagi, Lily Evans hits James Potter over the head.
With a textbook.
{ Hard. }
Of all the comprehensively idiotic things they had ever done, this had to be the most insane, reckless, downright stupid, and entirely incredible of them all. Only a Marauder would do something so dangerous and illegal for a friend.
Now, Lily was by no means terrible herself at Transfiguration, the subject fell comfortably somewhere close behind Charms and Potions. But to her it seemed that James Potter was one of those rather strange and annoying people who were brilliantly talented, infuriatingly clever, and happened to possess inhuman amounts of energy, all in the one being. He lived and breathed everything bar being sensible, the list looking something like —- One, Quidditch; two, Transfiguration — or at least showing off in Transfiguration and managing to wrangle a rare smile on to McGonagall's face and himself out of trouble at the same time; — and three, the only breathable substance actually necessary for human survival, namely air…And that was at a stretch, should the person compiling this list be positively obtuse and unable to think of another item.
So, of course he was an Animagus too.
Really, she should have guessed given the general consensus of their brilliance. But she's never admitting that.
Bastard.
Which is what she told him, with a few choice adjectives — all of which he'd heard multiple times before — and fighting the quirk of her lips, promptly after hitting him over the head with textbook very, very hard.
But being told about their illicit little adventures and actually seeing them transform were two completely different things.
The first she sees the three boys are Animagi, Lily Evans is bowled over by an excitable and overly enthusiastic black dog.
The stag snorts in what would appear to be laughter.
(When they're human again, both James and Sirius get textbooks over the head.)
— She had curled up on the couch when she thinks of it. Being curled up just like that but in a theatre chair, watching a film play across a huge screen that seemed even larger to her six-year-old self. She can remember the film clear as day and giggles as James sits down next to her. He shoots her a curious look. Lily shakes her head and waves him off, still smiling to herself.
She makes sure at the very least Siruis is listening, but she knows Remus has been casting them amused glances for the last minute or so. Once they get the reference, she doesn't want James to ever live it down.
Lily stands, reaching out and petting James Potter atop his messy head of hair, smiling prettily. Her green eyes glitter as she murmurs, innocent as ever,
'Night, Bambi.'
She's reached the top of the stairs before Sirius' jovial bark of laughter fills the room below.
