mary's death is important!!! it is important so sherlock stops being arrogant!! and it is important the show has conflict!!! john and sherlock need conflict or the show is stagnant!!!!
me, an intellectual:
in episode 5.8 of elementary, Jonny Lee Miller's Sherlock Holmes decides that he is far too clever to continue attending recovery meetings. Joan "played by Lucy Lui whose character is not a cheating hypocritical white male" Watson points out to Sherlock that addicts who continue going to meetings maintain their recovery better than those who don't. After some crime solving and self reflection, Sherlock takes Joan's advice and returns to regularly attending meetings wherein he acknowledges his arrogance and starts on the path of unlearning his arrogance. This happens as a result of mutual honesty and respect between him and his best friend/equal partner Joan "played by Lucy Lui whose character is not a cheating hypocritical white male" Watson and Sherlock's disposition for self-reflection and the best part??????? No women were killed to make male characters more interesting because Elementary is not written by misogynistic wankers who openly admit to not reading valid critiques of their show, but is written by decent humans that care about their audience AND the sensitivity of their content.
P.S. If you are anti!elementary, or a tjlc person pretending your fetishistic misogyny is lgbt representation, this post is not for you so please kindly don't interact with it.
