I hope the writers have a plan because it'll kill me if they write Quentin off the show
he is a great character, his character has really grown over the years and I love him working "with" the Arrow. How its grown over the seasons into a "partnership"
That is true that he did keep the secret of Sara being alive from Laurel
so really hope he sees why she is keeping the secret of her death from him. It'll be painful but they will all come out of this stronger and closer
