In addition to Potter's new study habits, the spy had noticed differences in the two Lion's behavior. Both Potter and Granger held themselves differently, more confidently. They acted more like pureblood heirs and less like muggle-raised magicals. Granger managed to tame that bushy mass she called hair, and had stopped trying to answer every Merlin-damned question in class. Potter's hair was still as messy as always (Severus figured it must be the Potter genes), but participated in class more than before.
