Poor Felicity. Not only has she now found out that her hubby-to-be has in fact got a secret son, she also finds out that other people already knew about this. First Thea reveals that she already knew about William, then it comes out that Barry Allen also knows about Ollies son, and then its let out that even Malcolm Merlyn was in on the secret. At least Felicity can take some solace in the fact that Diggle and Laurel were also in the dark on this one.
