I love the way this chapter flows and all the little details of how often Harry actually thinks of Draco and what Draco would say or do in response to his actions. The bit in the Observation exam where he was sure he heard Draco snort was brilliant, especially since he wasn't there. :) And the care with which Draco addresses every subject when talking to Harry is very fitting as well. The evolution of their relationship is exciting and smooth. I still feel bad for Hermione though. Poor girl.

Great chapter!
