She threw things into the trunk hastily, slamming the lid down when everything was packed. Unlocking the window with a wave of her wand, she pushed it open and shoved her head out in the cold, clear air that filled the night. After glancing around the room again to make sure all traces of her were gone, she levitated the trunk into the air and through the window (she's never liked doors much).
Taking off her shoes to make sure she didn't make a sound as she ran away, she allowed herself a few second thoughts before going through with her plan. Second thoughts had always been few and far between for whatever plan she had going on, but many filled her head as she dangled her legs out the window and into the night (maybe she doesn't have to go). With a sigh, she shoved all of them out of her head as she leaped from the window onto the grass, splattered with rain from the afternoon.
It wasn't that she'd woken up and decided to leave – or maybe she had (planning never was her strong suit). Things weren't right, and she decided that she couldn't be in something that didn't feel right. All relationships needed substance to them, more than just two people who enjoyed sleeping together. Soon as the thought had occurred to her, she'd packed her bags and was working on leaving. With a curse, she realized she'd left her wand on the window ledge and stood on her toes to grab it when she heard a shout – just what she'd been meaning to avoid with going to all of the trouble to take her shoes off.
"What the hell, Lily?" Scorpius demanded, sticking his head out of the window to stare at her, pale in the moonlight. "You've packed a trunk," he said, incredulous as he took in the sight of her, wand dangling from the fingertips in her right hand, left planted firmly on the trunk.
With a sigh, she shook her head hopelessly. "I was going to tell you, but–"
He glared at her, shocked that she wouldn't even give him the truth. "You wouldn't have told me. For fuck's sake, don't I even get a reason? Did I piss you off or something? Normal people don't just decide to run off from their flat without a fucking reason."
Desperate to calm him down without having to enter the flat, Lily shrugged with her mind reeling. "I don't think that I love you, Scorpius. And I won't stay with someone I don't love," she said simply.
Gaping at her, he tried to come up with a rational response before realizing he was talking to Lily Potter (and therefore all thoughts of rationality were null and void). "I guess that's it then…" he said, staring at her in wonder as she gave another shrug and turned her back on him, fully intent on leaving. "Grow up then, and when you find out no one else puts up with you like I do, don't coming back here to cry at me about how hard it was. Run off on me, just like you run off on everyone else!" he yelled, slamming the window shut.

Nothing was the same with Lily, yet her absence had pulled his life into an eerie calm with no upsets – there were no plates being randomly thrown just because she'd felt like it, no occasional ripped pieces of parchment scattered everywhere just because the place had been too clean, no Muggle appliances going haywire on him after she'd bought them because the Muggles had the best kitchenware. He never called her, never went looking, never bothered to Floo to Albus and ask how she was. As far as he was concerned, Lily was out of his life and wouldn't ever be entering it again. So he never visited spots that she'd frequented before, almost as though he was afraid of running into her.
He wouldn't be so angry if he didn't love her so much.
