Leto kept a strong rein on an ill-timed retort about saucy daleks. Instead, he loosened his arms a little -- not exactly pulling away, but acknowledging that perhaps he'd been holding her a little longer than what was proper. He knew he was in very real danger of turning the embrace into something for him instead of for her. Even still, he stayed very close. She'd asked for him to hold her; she hadn't said how long (her joke aside).
A small part of him wanted to insist that she tell him she didn't find what he'd done presumptuous; part of him wanted to hear her say that this had made her happy. But it was only a small, insecure part of him, and it was overwhelmed by deeper experience past his years. He had been born and bred to change the lives of others -- for good or bad. He would not dwell for long on the concern.
"Do you need anything?" he asked. Although he hadn't laughed at either of her jokes, he let amusement filter through his voice when he spoke. He wouldn't overwhelm her with too many questions or demand of her things that she wasn't ready to give. But if there were something she needed immediately, he wanted to give it to her.
