For those who watch How To Get Away With Murder , Can you believe what the writer/s did?

I thought so much of him avid his past was hidden and secretive , that the more he found out the more it would change him . Making him even more interesting bad thrilling to watch . Especially the last episodes they where really building up the tension making it seem as if we where about to see a different side to him . And that scene when he fired his lawyer and was with the two FBI agents . I thought they was the moment we where going to see strong powerful Wes pulling all the strings and playing everyone .
My point it they left so many question , the left us unsatisfied.

Maybe they will find a way to bring him back . To me it seemed like the whole show was based around him and Annalise keating , with everyone else just being additions to the story .Perhaps this is their last season ?
