"So this is my theory. Olivers ultimate sacrifice is not his life, but his heroism, and the ending of ?Crisis (and that of Arrow at the same time) may see Oliver revert to a regular, self centred rich guy without any knowledge of the heights he once achieved. Whats worse? Living in a world you know is wrong (Invasion!) or living in a world without knowing how wrong it is? Heartbreaking, right?"
That'd suck man honestly, Oliver has been such a great leading character
