Severus apologized for what he said to me that day, and I apologized for accusing him of fraternizing with Death Eaters, to which he finally admitted that he had been corresponding with Malfoy, but he would stop if it really bothered me. Sometimes I still get the nagging suspicion that Sev is still talking to Malfoy, but I push those thoughts out of my head nearly as soon as they come to me. Severus promised me that he would stop. And if I can't trust him, who can I trust?
