Chloe Sullivan
The type of character has been around now for awhile but Felicity can't be the next Chloe Sullivan...not entirely at least. Chloe was not a real character in the comics back then so she could never get with Clark even though she loved him. Now I'm all for sticking to the original story but in certain cases I can change my mind. Olicity needs to happen. I'm sorry but Laurel just isn't Felicity. Besides the comics can change to suit new lore. It's happened before, It's already happened with Diggle being added to them here.
on the p.s. side guess who the Green Arrow married in Smallville: Chloe Sullivan, it seems in TV adaptations, Oliver likes the idea
