Link tenses, just briefly, when she leans against her shoulder - an instinctive reaction of surprise.

He...he hadn't expected her to do that. Hadn't expected her to lean right up against him, her head on his shoulder. She's warm.

She's trying not to think about using him for support - but all Link wants to do is be her support. He wants to hold her hand and always let her lean on him.

He doesn't hold her hand. He's still not bold enough for that. But...he leans his head, just gently, on top of hers.
