She had thought for sure that when she nuzzled into his chest he would have pulled away, that he'd push her off of his bed or resort back to torture but he didn't. It took her for a shock, just like he had for the past hour. He was still being so gentle with her, loving almost. Hell he was being loving towards her and it was a welcome change, though it did unnerve her if only a little as Katherine believed part of it must be a trick. Surely he was acting this way just to get under her skin? Perhaps.

Klaus and Katherine, however, were not in a relationship nor were they normal people. Instead she remained silent, still pressed against him as she listened, waiting for something to happen.
