Aww, Snape is such a sweetheart! He's so gruff but he jumped in to help Lola without hesitation. That relationship is so sweet. 

I don't doubt that the house feels crowded. Tobias would not be an easy person to live with. Poor Snape. In less than a year he went from living alone to living with a kid, his estranged father, a poorly behaved dog, and a tarantula he can't dissect. 

I like how Severus uses a bit more magic in this chapter as well as Harry's view of Severus.
