Chapter 2: Telling him

The rain was pounding the tent, tears were pouring down Hermione's face, and the excitement of a few minutes before had vanished as if it had never been, a short-lived firework that had flared and died, leaving everything dark, wet, and cold.

Ron wrenched the chain from over his head and cast the locket into a nearby chair. He turned to Hermione.
"What are you doing?"
"What do you mean?"
"Are you staying, or what?"
"I . . ." She looked anguished. "Yes — yes, I'm staying. Ron, we said we'd go with Harry, we said we'd help —"
"I get it. You choose him."
"Ron, no — please — come back, come back!"*

He got out of the tent and she followed him.
"Ron, come back!" she called him. He stopped and turned around to face her one last time. She looked at him as tears ran through her pale face. "You can't leave me! Please!" she cried. He looked at her. Part of him wanted to stay with her. It broke his heart in million pieces to see her crying like she was. "I'm pregnant." she suddenly confessed. He looked at her, shocked. Had he heard her correctly? Did she just say she was pregnant? "And before you start doubting about it, yes, it's yours." she added. She looked at him. "It's always been you, Ron. No one else. Just you." she finally said. He kept looking at her, trying to move, trying to digest this huge piece of information. When he still said nothing, she burst into tears. "I can't do this alone. Please, don't leave me. don't leave us." she cried as she ran a hand through her tiny bump. She stared at him, scared, crying without console. Had she frightened him with the news? Would he stay with her or would he leave? Her stomach twirled and she felt sick. By now, she was crying hysterically, and all the efforts of her body to make her stop, in fact, were making her sicker. Suddenly, she felt hands grabbing her cheeks and lips crushing against hers. Ron was kissing her. HE was kissing HER. She wrapped her arms around his neck and pressed her lips against his, returning the kiss gently but passionately. They kept kissing for several minutes until she broke it off. He looked at her, quizzical. She bent over and thew up on the grass next to him. It seemed non-stop. She didn't know whether it was because of the stress of the fight or the morning sickness. She was sure it wasn't the kiss. Not at all. She had loved the times Ron kissed her. In fact, she missed them.
Ron looked at her worried. He rubbed her back, trying to reassure her. When she finally finished, she straightened herself up and looked at him, sobbing. He handed her his handkerchief and she cleaned her mouth. He wrapped his right arm around her waist while he rubbed her barely swollen belly with his left hand.
"How... How far along...?" he managed to ask.
"20 weeks. That's nearly 5 months." she answered, calmly.
"when did you...?" he asked
"a few weeks ago. At first I thought it was stress because of all this. But then, I grew more tired and sicker and I realized it was much more than that, so I took three muggle home pregnacy tests. I wanted to tell you, but... it never seemed to be a good time." she said looking down at her belly. He nodded slowly.
"So, when do you think...?" he asked.
"Our first night at Grimmauld Place. Maybe one of the few times after that. I'm not so sure. We didn't... I didn't cast any contraception charm or taken a potion, so..." she said. He nodded again. He tilted her head to him and kissed her one more time.
"so... a baby." he said when he broke off the kiss. Their foreheads pressed together and their eyes closed. Their breathings were slow and syncronized. She sighed.
"yeah... a baby." she whispered. Rain was still pouring on top of them, but it didn't matter.
Harry was looking at the whole scene from the tent, wondering what was actually happening between them.
