Nyssa wants to serve up Malcolm on a platter with the help of Oliver. But you have to wonder why she can't just kill him herself.

Oh look. It's Renee (or Rene) Darhk. Is this when she announces she's going to put in a late-to-the-party bid on the mayoral race? I guess it would be a better show if a nasty bitch ran the place. A lot more work for the superheroes, keeping them in business, ya know?!
Added:
Felicity looks worried about something. Whether it's as a result of her business dealings or her personal life? We'll just have to wait and see!
Added:
Oliver looks fairly serious as he conducts this conversation. Maybe it's about the Calculator. Maybe he learned something about the dude and needs to share it with Felicity.
Added:
If Oliver is back at Palmer Tech, there must be new business going on. Perhaps he's there in his capacity as the mayoral candidate. Or Felicity was allowing him to speak as such to her company.
Added:
Oliver sits with the man known as the Calculator. Rumor has it he will also be her father. I can't imagine Donna Smoak dating this guy, can you? They look happy now, but I bet that's gonna change. You don't get a code name for nothin'.
Added:
There is a meeting at Palmer Tech and both Dennis and Curtis are in attendance. Curtis is all decked out in a suit. It must be a very important meeting.
Added:
Curtis has the same smile on a different day. Over the course of these photos, we see Curtis in three different outfits, so several days must pass. It's been a while since we've seen this kind of business action!
Added:
Felicity is definitely back at Palmer Tech. This fellow is Dennis. I'm not sure who Dennis is who how he'll be connected to the story, but we'll soon find out!
Added:
Curtis Holt is smiling. Perhaps he's welcoming Felicity back to work. Has he been holding down the fort while she's been gone? Maybe she's been working all this time and we just haven't seen it.
Added:
Felicity is cool in a nice blue blazer. She appears ready for whatever comes her way. Seems like she goes back to work at Palmer Tech.
Added:
Perhaps Nyssa is making her entrance. She's back during "Unchained" to make her move. I'm assuming this is her move against Malcolm Merlyn, but I'm not sure why she'd have to come to Star City to do it, since he should be ruling of the League of Assassins out her way.

Arrow Quotes

Oliver, sometimes the greatest act of love is no action at all. It's her life. It's her choice.

Felicity: Excuse me?
Oliver: Well, I thought it was time you got a code name. What do you think?
Felicity: It's perfect.
Oliver: I was gonna go with Oracle, but it's taken.
