This is a great story and a great chapter! You have an amazing deal of tension and the best kind of mixture between animosity and caring. This story could really get a lot of appreciative readers and reviewers.

However, you have many mistakes, words are missing, words are in the wrong tenses... I think that that is taking a full frog off of your score/rating. You need to edit this and fix everything. I don't know if these are just typos or if you just didn't realize, but you need to fix them.

Here are some examples:

he was not about left Harry on the side of street like some unknown beggar. (about to leave)

“Potter,” Snape’s deepened, (Snape's voice deepened)

Snape stepped a few paces closer, making have (making Harry have)

You Harry Potter, the star of Hogwarts and Savior of the Wizarding World?” (You,)

He hated when Snape reminded him of his famous place (reminded him of his fame)

More concerned (More like concerned)

“Nothings wrong (Nothing's)

“Nothing much,” he answered. “Just a few bruises (this is missing the ending punctuation)

walked over to Harry and setting a potion down on the table near the couch. (set)

to make sure his swallowed. (he)

There are many more. Please take the time to fix them or get a betareader. :) I have to rate you a 8 for this chapter, if there weren't so many mistakes I would have given you a 10.
