Sleep technically wasn't needed for them but tomorrow? When they woke, she knew she'd find herself face to face with Klaus. Whether he was like this or the man she'd come to know, she wouldn't know until morning. Ether way she could deal with him, more so now that she knew what he'd done. Now that he'd actually expressed emotion and feeling. She fully intended to rub it in his face, actually. There was nothing he could do to take that away from her. Niklaus the big bad original had feelings and he was expressing them.
Whimpering softly as they continued to kiss, not because it hurt or anything but because it was a much needed end to her relief, Katherine nuzzled further against him, sealing the rest of the gap that he hadn't. She allowed him to move her, positioning her hands wherever he wanted them. Hell, so long as he didn't stop this, she'd let him do whatever he bloody well pleased. Smiling against his lips Katherine let her fingers run through his short hair.
