Chris heard Lena's answer and she sounded tired. "I think we should probably be heading to the Common Rooms now. You sound like you are just going to fall asleep right here soon." He said with a small grin. His grin got a little wider at Lena's comment. "I'm sure you will be all I can think about as well." He told her giving her one last squeeze before letting go of her and standing up. He then offered his hand to her to help Helena stand up as well.
