Riza smiled when the god was glad that she was looking after him. She felt good inside that she was doing some good. SHe honestly didnt know what to say to him for she was somewhat out of words. She sat there though in thought. Thinking about what she could do to help make him comfortable. She felt nervous around him, as well as new to helping someone else that didnt involve saving their life. 
After a while, she had come out of her thoughts to have seen that Loki had fallen asleep. She decided to roll over to her desk, drink some of her cappuccino before looking to see if JARVIS still had connection to her appartment computer and lab. She pulled up some plans she had designed and was flicking through them. Riza had stopped however to hear the sounds of sniffles and what sounded like crying. Looking over to her bed, the young Stark had noticed that Loki was crying. Rolling her chair over, she stopped it next to the bed to cautiously put a hand on his shoulder, rubbing his arm softly. "Shhhh...Its okay Loki. I'm here."
