Oliver winced, hoping the 'Oliver like' scent to his sheets wasn't of sweat. He might have collapsed on his bed earlier, his jelly legs unable to take him all the way to the shower right away. One might think he was a right dumbarse for going back for yet another workout today, but there was nothing for it. He had no time to waste and - he'd thought of all this already, hadn't he?
He moved up behind her, placing a hand on Tonks's shoulder with another smile as he picked up the book (he'd left it at the foot of the bed, apparently) and threw it under his bed where it belonged. "I was just going for another run. You're free to stay here, though. Soak up all the... Oliver... smell ... as you like. I'll be back soon."
