I love this chapter. Harry teasing Snape by calling her Tabby is too cute.  I'm a sucker for good Snape-Harry conversations and this was a good one. Snape speaks to Harry with respect and in an age appropriate manor.  Harry's concern about Snape's mood needed to be addressed. Snape, as usual, popped off harder than he should, but got ahold of himself in the end. It would have been easy to just pat Harry on the head and tell him to run along. I'm so glad Snape didn't do that. He really does need to get an emotional outlet arranged though. 

Tobias needs to get his shit together. 

Harry is going to be a rock star!
