Her serious tone and expression shocked him a bit. The idea of her coming and finding him in some state of being ripped apart wouldn't make her feel any better. For a moment he considered trying to convince her that it wasn't something she needed to bother with, but he hardly saw the point. Tonks wasn't the type of woman to give up, especially when he saw the determination in her eyes.
"I promise I'll keep the journal with me when I go from now on, well, with my things," he usually kept his things somewhere and tried to return to them in the morning. Even that took some time. "I'll let you know how I've doing. I promise." He was locked in her gaze, hoping she could see the sincerity in his eyes. He didn't like breaking promises.
"If you had stew waiting for me after every full moon I'd be thrilled. I wouldn't get tired of it, at least not for now." he replied with a smile. Her cooking was wonderful, the idea of him coming home to her cooking, even once a month, was wonderful. Like a proper family. For a few moments he just looked at her. Last night in the forest felt years away.
