In the current episodes of Arrow, Felicity Smoak has received a flash drive with an enormous amount of hacked data from the NSA that is slowly pulling her back into her Hacktivist days. She originally went looking for information to clear John Diggle, but she ended up with a treasure trove called Pandora from a group called Helix. They want her to continue using it and as of the end of last week's episode, she plans on it. But with almost anything in Arrow, you have to wonder when and how will Oliver Queen find out and more importantly how will he react. Actor Stephen Amell told EW.com that it won't be fore several episodes and his reaction may be surprising:
He knows that she's into something, and he knows that she doesn't want to tell him about it, so he's dealing with that in his own way. For Felicity, it's not something that she and Oliver discuss until they have what is actually an adult conversation about it in [a future episode].
Arrow airs Wednesdays at 8 PM on the CW.
