Obi-Wan cannot help the happiness he feels at Padmé saying she adores him, and still would no matter what he looked like. He adores her too, and considers her a good friend; it's what could grow from that that he's unsure of, and of how aware she is of how her words could be construed.

It takes a slow, measured breath before he can turn his mind away from the thoughts her last words have conjured - and because he has so recently finished meditation and is still very connected to his surroundings, he feels Padmé's embarrassment, and can only surmise that she's also noticed how her words could be taken.

He decides to stay within familiar teasing territory as they enter the manor, and says "I should hope you would still adore me, as it would be your fault - and your cooking - that would make me grow so large you would have to roll me around everywhere." His free hand instinctively moves up to hers on his arm and gives it a light squeeze. "Of course, then you could just use my body as a barricade should the need arise, and I would still feel useful."
