ok .....spoilers !!
I saw this live, and Felicity lives but wont ever walk again, so she will
be like professor x I guess.
Although in previews they show her and oliver in a car and she looks normal,
and they were leaving a funeral, so somebody else dies, and it upsets felicity
and she tells oliver to kill dark, though she says "him" so could be someone else.
We find out at end that darks wife who GA saves, is as bad as dark, and in on the plan
with him.
I have to say I think the island part of the show is insane and bizarre, and I just dont see how the producers could think it is good story, or that it is good to mix that in with present day
story.
It should have been dropped, makes it hard for me to watch the show at all.
