"Nice," Ron said with a quiet scoff, letting his fingers play up a little from her shoulder into her hair. He was feeling a bit thick. It wasn't that retorts ever really came to him quickly enough, but he was having a particularly hard time thinking of what to say now. There was something about feeling her weight against him that was very distracting, in a reassuring sort of way.
Then she saved him the effort, which, he thought, was only fair since it was her fault he didn't know what to say to begin with. He gave a start, but recovered quickly. His hand pushed further into her hair and he twisted a little onto his side to put his arm over her waist, wedging his shoulder uncomfortably up against the headboard; he hardly noticed. He wouldn't have moved even if he had, wouldn't have done anything to change it.
