This chapter worked well and flows nicely from the previous ones. I suspect Lucius is going to have a difficult time getting Harry since there's no real trace around of "Harry Potter". In the meantime, Tom has to be feeling more than a touch insecure considering that Harry's managed to battle back from everything he's done to him and is rather more capable now, despite Azkaban's baleful influence. I can see several of Harry's friends rallying to him as needed and I quite expect Albus is going to have difficulty regaining whatever control he thought he had; that he likely won't be able to nor will Harry want him to just warms my heart. I have to chuckle at Severus Snape's reaction as he finds out that once again a Potter has bested him.
