Eventually Odin would put Bella's mind to rest in that he could, most of the time, rein in his clairsentience. Unless he was extremely curious or the events connected to the object were extremely powerful, he could ignore it. when he touched Bella's cheek he saw nothing as he wanted to see nothing but her face in that moment. When he kissed her, however, he did see her first kiss, just a flash of it which he attributed to the fact that it was directly connected to what was happening now. She'd been young, probably inexperienced and, he could see, caught by surprise. She'd had no time to experience the kiss, or even, he assumed, to decide whether she'd liked it. This wasn't going to be like that.
Without deepening the kiss or forcing any sort of pressure Odin didn't pull back right away, wanting to feel her and, more importantly, wanting her to feel him. Odin wanted to give Bella the time to savor the experience. Eventually he deepened the kiss only a little before pulling away, and brushed his nose against hers affectionately.
