Then that means that..... Game of Throne all over again xD
Incest lovers rejoice? :P
Well I highly doubt that, tho you never know.
I would tho totally buy that Isabel was lovers with Robert. ooh.
How do you find that, fancy?
Or maybe Moira had an affair... ok j/k that would be too far as well I guess. xD
But from the attitude of both of them it gotta be a love issue for sure of some sort. Or something deeply emotional, tho I wouldn't count or count out murder completely.
Much interesting question is, now that Moira has returned, does Oliver stays as a CEO partner or Moira gets back at her position and if not at what exactly post she will be leading. And I wonder mostly will Oliver lean towards Felicity or stay with Isabel(which I prefer over Felicity atm, bcs she ended being much more lively interesting and deep character with the proper balance between dark and good in her FOR MY TASTE NEEDS personally). I don't know how are everyone else on that one, other than the "I'll even commit murder for Summer Glau if I have to" statement that I also share with everyone else here, but I mean I have some other sort of feel about Isabel on top of that layer, which is again thx to Summer's unique and great talent I am sure.
