It's a fine line he tries to tread, paying attention to everything happening around him, but pretending that he can't feel Padmé's feelings - and really, that's as much for himself as her, because he has no idea how to comfort her, isn't even sure if he has the right, when he already feels so responsible for the situation they've found themselves in.

Because of his conflicting feelings, he's been focusing on the practical, and he worries he's been isolating her more than is necessary. She needs contact, emotional warmth now, especially after Anakin...

It's a miracle she's alive, and speaks solely to her strength of will, something he's always admired in her.

Tossing down the spanner before he starts bashing the equipment with it, Obi-Wan stands up and gives her a grateful smile. "Dear Force, yes. Please, distract me from this rusted hunk of shite before I chuck it all out the window." He plays up his frustration (though he doesn't have to play it up much, sadly), hoping to make her laugh, or at least smile.
