Good decision. I just hope the writers got this news early enough to give the show a somewhat decent send off. The writing lately has been

Nobody cares about Margeaux trying to act tough, no one cares about David having lymphoma (he should've stayed dead to be honest), and no one cares for the lack of character development and accelerated romances and story lines that make no sense. I'm still not sure if Victoria is dead for sure but lately the episodes have been 58 minutes of beating around the bush and then 1 minute of actual shock/storyline. It had a good run but honestly this story could've been told in 2 seasons. The initiative and killing off key characters like Aiden, Daniel, and Conrad took away from the central themes and draw of the first season. With the final episode titled Two Graves, I think it would be only fitting for Amanda and Victoria to die but the writers will likely go for some cliché ending with Emily and Jack having some pseudoromantic happily ever after and David or that obnoxious cop dying. Fans of the show would probably be fine with Charlotte and Margeaux being the two graves too
Victoria was the best part of this show and her clashes with Emily were the highlights. Take that away and there really is no show, so I'm glad it coming to an end and I'm hoping for a good finale.
