Because of the Azkaban escapee, Sirius Black, Severus is sent to stay with Harry during the entire summer, never making a sound nor leaving the boy's side. He could not speak, nor could he defend Harry against anyone other than the criminal on the loose, however Severus does something that no other adult in Harry's life had done before...he listened.

Severus Snape comes across a runaway… the boy-who-lived to be exact, and drags him back to his home where a struggling Harry is surprised to find Luna Lovegood. Severus had agreed to take custody of Luna at the start of the summer, but taking on the boy who lived to be a pain in his arse as well? Harry is finding out quickly that he’s got everything to lose… and everything to gain. In response to the 'multiple challenges', 'this is home', and 'father to two challenges'.
