Descripción:

Severus gives Harry Patronus lessons, having convinced Lupin to lend him the Boggart. Lupin, however, requested to be present, and is surprised that Harry is the student Severus was tutoring. He is also surprised that Severus can produce a corporeal patronus and confronts him about it's form after Harry leaves. This conversation turns into Lupin confronting him about why Harry looks like him, which Snape refuses to talk about.
