There were few people in the world Charlotte adored more than her nephew. She had spent a lot of time with him while he was growing up and now he was such a wonderful young man. She very much wanted to meet the boyfriend and make sure he was going to treat Jamie the way he deserved to be treated.
And it would keep her mind off her sick brother. Thomas was essentially her hero. She couldn't handle him being ill.
She knocked once and then simply used her key to let herself into the apartment. "Hi!" she said cheerfully, locating her nephew easily. "I brought you some cotton candy in a bag!" She didn't explain where she had gotten it or why, she just handed it over.
