No, it wasn't hard to guess it about him. Not when she was finding some excuse to be looking at him at all times. Out of the corner of her eye, or whatever.

When she entered the kitchen, she set off towards the sink first, to check that plate she'd broken earlier. ... she didn't even know if he'd managed to hear that, though she hoped not. Good thing that Godric had probably taken care of any leftovers that MAY have been on the plate at the time.
The distracted 'Reparo' seemed to have worked all right.

She was glad that she's managed to put away most of the leftover food already... she shook her head at herself at that. She wasn't facing a week of weight loss right NOW, which he was. Maybe they'd both be able to eat more, what with the likely kiddies enthusiasm.

"How 'bout I start washing the dishes, and you finish with the table?" What? Giving him space, minimising the chance to trip, and... taking up on the work that had more to be done? Seemed a sensible labour distribution to her.
