Michael J. Fox will reprise his Emmy-nominated role of Louis Canning, which originated on The Good Wife, in season 4 of The Good Fight.

If Fifty Shades of Grey and Harry Potter ever have a cross over, Severus Snape’s new name should be Morally Grey. Get it? It’s because the audience never really knows the true nature of Snape’s moral compass. Yikes, anyway the point is that Snape is the most complex character in the entire Harry Potter series. Both the movies and books do an incredible job of making Snape’s motivations compellingly vague. Snape will sometimes do something totally mean, but in an instant he’ll also save the day. Although Snape’s actions speak very loudly, he also has some of the best lines in the entire franchise. Check out the list to see the quotes that reveal the very best and darkest parts of Snape’s character!
