Blaise had been helping his stepfather secure a portkey to Italy. It was surprisingly easy to find someone to make it when a person had enough galleons to toss around. It was harder to cover tracks so the Ministry didn't come asking questions and people remained anonymous. He had paid an exuberant amount taken from his mum's account to pass on the charmed shoe to the Azkaban escapee.
Tracey was the bright spot in his day. He had been so stressed over hiding Ae-cha and getting rid of Cyril that he had been neglecting his friends. He was so happy at having Ae-cha back that he had spent the whole night playing with her, dolls and tea parties and all.
Dressed like a muggle, in trousers and a button up shirt, Blaise apparated to Tracey's and took the steps a few at a time. "I will just come up." He said as he pushed open the door of her bedroom.
