Ron wasn't really sure how to answer that question as he wasn't entirely sure himself. He'd just known that he had to tell her about Harry and he just knew where to go. "I don't really know. Well, I know how I got here. I got here on my broom. I don't know how I knew where to go though. I just did." he finished, looking utterly confused. Hermione found herself grinning at how cute he looked at that moment. Where did that come from? she wondered, now also completely confuzzled. "You ok?" Ron asked, noticing her bewildered expression. Hermione smiled quickly and nodded.
"So, are you ready to go?" Ron asked, getting to his feet. Hermione looked up at him confusedly. "Ready to go? Where?" she questioned. He looked at her for a second before answering. "To go and find Harry!" he stated as though it was the most obvious thing in the world. Jumping to her feet, Hermione began packing with incredible speed. Within five minutes, she was dressed and almost ready. Tiptoeing to the door, she opened it quietly and was about to walk out when Ron grabbed her arm. "Where are you going?" he asked. "My broom's outside your window!" She nodded, before gently pulling her arm from his grasp. "I can't leave without telling my parents." she whispered back. Ron nodded and went to walk back to the window to wait for her return. After a moment's pause, she turned back to him. "Want to meet them?" she asked hesitantly. "Only, it'll make them less nervous if they know that I'm going with someone with such incredible strength and intelligence," she added mockingly. Ron grinned and followed her down the hall.
In what seemed like no time, Hermione had her arms around Ron's waist, holding on for dear life as they flew back to The Burrow. Hermione had introduced Ron properly to her parents, explained the situation and spent an hour trying to reassure them that she'd be ok. Before she knew it, they were descending and her feet were skimming the grass in Ron's backyard. When they'd come to a complete stop, Hermione finally broke her deathgrip on Ron and dismounted the broom.
A shriek cut through the silent night and Mrs. Weasley came running across the lawn. "Oh, Ron! What on earth were you thinking!? You can't just disappear in the middle of the night without telling me where you're going!" Ron opened his mouth to defend himself but Mrs. Weasely held up a hand. "No, Ron. A note saying 'Gone to get Hermione' is not an explaination!" she snapped. She turned and looked Hermione over, who was hovering awkwardly to one side. She always got a bit nervous when Ron or his brothers were getting in trouble. "Hermione! How are you, dear?" she beamed, grasping Hermione's hands. "Oh! You're cold as ice! Come on inside for some hot chocolate." She shot Ron a glare and lead Hermione inside, Ron trudging after them.
Once they got inside, Ron pulled out the letter and handed it to his mother. "Here's your explaination." he muttered, turning and walking out of the kitchen. Hermione watched him go with a mixture of disappointment and shock. She was surprised at the way he'd given his mother the news of Harry's leaving and a bit hurt that he'd left her without a word. Thankfully, Mrs. Weasley decided to get Hermione settled before she read the letter. "Come upstairs and we'll get you all set up." she said kindly, gently guiding Hermione upstairs.
When they reached the landing of Ginny's room, Hermione automatically turned toward her door, but Mrs. Weasley stopped her. "Oh no, dear. I'm afraid Ginny's a little under the weather. Wouldn't want you catching anything." Sighing, she looked at the ceiling. "I'd set you up in Fred and George's old room, but goodness knows what's in there. No, I guess you'll just have to bunk in Ron's room. Will that be ok, dear? It'll only be for tonight. Tomorrow we'll sort it out." she smiled. Hermione nodded and followed her up to Ron's room.
Knocking on the door and getting a grunt in response, Mrs. Weasley opened the door and put Hermione's bag next to the doorway. "I'll just go and get your bed, dear." she said softly, turning and pulling the door to. Ron was, lying on the bed, arms under his head, looking at Hermione in surprise. "I guess we're roomies." she stated, smiling at him. Ron cocked an eyebrow, still shocked. Leaning back against his pillows, he shrugged. "Maybe I don't want to share my room." he said nonchalantly. Hermione also shrugged. "Well then, maybe I'll leave it up to you to tell your mum." she replied. "Tell me what?" panted Mrs. Weasley, pushing open the door and pulling behind her a camp bed. Hermione looked back at Ron, a challenging grin on her face. He glared back at her before rolling his eyes. "Nothing." he muttered. Mrs. Weasley studied her youngest son for a second before heaving a sigh. "Well, if it's nothing, could you help me with this thing please?" she asked, apparently no longer angry at him. Groaning, Ron got to his feet and helped set up the camp bed. Soon it was next to Ron's, ready to be slept in and Mrs. Weasley bade them both goodnight. "Oh, and no more sneaking off." she added at the door, winking at them before shutting it.
