Sirius did not feel daunted by the judgment of his father, at least not in a way that mattered. He was sure of it. He was convinced. Anyways, he would not fail — he took Defense Against the Dark Arts as one of his favorite N.E.W.T. classes, and he was a member of dueling club. Miss Frost may be a classmate, but she wasn't in dueling club.

Sirius bowed as bidden, and then cast the ebublio jinx to start — he rather enjoyed trapping opponents in a giant bubble.
