Your unshed tears would fill the oceans
As mine have drained the seas

The Hogwarts Express shone rich ebony in the early morning night. A band of unusually subdued pupils swarmed next to it, as drunken bees around a flower. The new livery of the train was a clear tribute to the dead headmaster, and the students, most dressed in dark school robes, looked forlorn and lost.
Luna Lovegood surveyed them quietly from her perch on top of a few trunks, her spindly legs not long enough to place her feet on the sticky carriage floor. Most noticeable about her was the absence of her eccentricity. No Quibbler, no butterbeer corks, not even a smile.
Neville Longbottom stumbled onto the train with a scarlet face, clutching Trevor tightly in one hand. He caught a glimpse of Luna and shot towards her, Trevor escaping from his grasp and settling between the two trunks.
'Can I sit here?' he enquired carefully, indicating the trunk next to hers. She shrugged and leant her forehead against the window, gazing emptily at the giant silhouette of the castle. Neville sat awkwardly. She obviously did not wish to talk to him. He hardly remembered the previous few days' events but much of his recovery was flavoured by Luna. Her face haunted his hazy consciousness as she was constantly by his side in the hospital wing and at the funeral.
He found himself watching her hand, on her lap. It seemed so delicate, pure white tinged with faint red scars, from botched potions experiments, no doubt. It suddenly went limp and her breathing became slower. Neville quickly let out the breath he was unaware he was holding. He chanced a look at her face, which had softened in slumber. Her wispy hair was pulled back, her innocent, sad expression evident. The faint light gave her an unearthly glow. Neville twitched. He had never so strongly about anyone, except Trevor, but he knew that this was quite different.
He glared at his scarlet hands, wringing them and trying hard to think of other things, but the girl beside him held his thoughts with an iron grasp.
After a rough ride through the hills, she sprang to life, moving jerkily and gazing at him with fearful eyes.
'How long was I out?' she asked uncertainly.
He shrugged, time had slowed the second he sat down.
The train rumbled through an overgrown area as she cast her shining eyes over him curiously. He cleared his throat and began, 'I meant to, erm, thank you, for um you know…'
He gulped and her brow creased delicately.
'…well for being there, in the hospital wing. It meant a lot… I was happy you were there and er…' he trailed off sadly, looking away. She placed one of her hands over his.
'That's what friends are for'
He nodded quickly,
'Yeah, well thanks.'
'Are you alright now?' she enquired nonchalantly.
'Oh, yes. Are you?' he attempted a small smile.
She shrugged, her eyes hardening. 'I've been better'
He opened his mouth in a last desperate attempt,
'There's nothing anyone can say is there?' she cut across him softly.
He shook his beetroot head,
'Then don't.'
She leant her head on his shoulder and let her eyes haze over. Trying to ignore how red he was, he blew upwards into his fringe and settled back against the carriage wall.
A few hours later, the train ground to a sudden halt, throwing the slumbering pair forward. Neville woke with a start to find Luna's arms loosely around his waist and she lifted her head.
'Home already?'
She gave him a sleepy half smile and nodded. Catching a glimpse of her father on the platform wiped away her smile.
'Are you going to Bill's wedding?' she asked quickly.
'Yeah I think so'
She struggled to her feet, 'I'll see you there then,'
He nodded mutely as she walked away. He could still feel her clinging to him, the brush of her hair against his skin and her arms, light as air. He watched her retreating back and his chest hurt.
'Come now, Neville, let's go and see your parents. They'll be glad to know that you're safe- they do understand these things, you know…'
His grandmother's voice floated through his head as he considered Bill's wedding.
He didn't see Luna's teary eyes follow him out of the station.
