Review: to be honest the episode was great! It showed more about the drug and more about how the family now perceives Finch. The way he is now on the field and how advantageous the drug is. But the problem is if it continues to have a case being solved every episode the element of a lack of surprise throughout the whole episode will make it boring.
Even though the last few minutes showed a cliff hanger (nurse part) it still made the whole episode predictable and kind of slow.
