While I’ve nearly caught up on Arrow, I’d like to mention a few this, like how in S4 E14 ‘A.W.O.L’ Felicity Smoak is more or less visited by Death from The Endless.
Now we all know it’s from Felicity’s goth phase when she was younger (also shown in S3 E5 ‘The Secret Origin of Felicity Smoak’), but she might have once heard about The Endless and copied the way Death was dressed, yet there’s a good chance that Death, (who can take on any form therefore would of toke the form of Felicity dressed as Death) was there to guide Felicity and who’s presence means to forewarn her of a close friends impending demise (hence Laurel Lance).
The Endless, oldest to youngest: Destiny, Death, Dream, Destruction, Desire, Despair and Delirium.
I couldn’t help but notice Oliver Queen looks like Destruction, if so then(theoretically) one could say Felicity Smaok and Oliver Queen are actually Death and Destruction. (just a thought)
And if so it would be great if Death and the rest of The Endless turned up from time to time, (which also means there could be a chance they could turn up in Constantine)
