Liz was relieved when he didn't move away from her. She was nerves about kissing a man of her own free will. She was grateful to him for keeping his hand on her cheek. It helped her focus. She noticed he closed his eyes. She didn't want to closed her eyes. She wanted to watched his reaction. When the train lurched she wrapped her arms around him to keep herself from falling forward. She liked the way he felt against her.
