Tonks knew now that staying at 12 Grimmauld Place had been a bad idea. She had plenty of other friends she could have imposed herself on. And okay, being in headquarters was convenient. And she'd be easy to find when they got the all clear on her own flat, so she'd be able to go back as soon as possible. And she'd be safest there, if Death Eaters really were considering attacking her, it wouldn't be too unrealistic to say they might find out where she was staying and attack there instead.
When she'd got up late at night, and wanted a glass of water, she could have gone to the bathroom. But instead she decided to get one from the kitchen instead, she had the idea of maybe making a snack too. So she'd had to walk past the door to his room. Remus leaving the door standing wide open was hardly her fault. It was practically an open invitation, so perhaps Tonks couldn't be blamed for walking in.
It was what she wanted after all. All the time she'd spent waiting for him to realise how she felt. It was bound to work out between them; everyone said so. Even if so far he'd refused her, and she'd had to turn down some other very tempting offers. She would wait for him, however long it took. Though sometimes, lying awake in the early hours of the morning, cold and alone, it seemed pointless. It might never happen.
He was asleep, though he half woke up when she sat on the edge of his bed, and he didn't object when she lay down next to him. Or even when she cuddled into his side, shivering slightly until he relinquished some of the blanket for her to use. It had been warm, and nice. Remus relished the comfort of another person.
When they'd woken up in the morning, she'd reached out to touch him and he shied away. He couldn't meet her eye, and they rarely spoke of that night again.
Tonks knew she loved Remus. But in time she came to realise that she could not force love on a broken heart.
"It's not me that you love"
Remus was cooking, and just for a split second he paused, the wooden spoon still in the saucepan. But just for a second, before he continued stirring.
"No. No, it's not."
