Yep, it sure looks like ol' Double Down has a cursed deck of cards fused right to his skin, doesn't it? Those aren't tattoos at all, but an actual deck of cursed cards, if we're to understand the lore.
Added:
Hey! It's Teen Wolf awesome dad Chris Argent! Looks like he's gone all bad as Jeremy Tell. In the comic universe, Jeremy Tell is Double Down, a con man and gambler who gained powers when a cursed deck of cards bonded with him. Huh. Waddya know?
Added:
Nope, it's not an earthquake (unless that's a baddie's clever name), but Curtis is right where Felicity likely put him for safe keeping.
Added:
Uh oh, Curtis Holt isn't getting the best impression of the Arrow lair, is he? Looks like he was either shot, or just thrust himself to the ground in abject terror. I'm betting the latter. We're with you, dude!
Added:
Those tables look nice and sturdy. Awfully handy when you're dodging incoming gunfire such that Felicity seems to be doing. She's going to need to start dressing more comfortably if this is to become a common occurrence.
Added:
Wouldn't it work better, Felicity, if you were looking where you were shooting? I mean, sure, it might be a little bit scary, but you have bigger cahones than that, right? C',mon girl! Turn around and get 'em!
Added:
There has obviously been a breach in the Arrow lair...err, cave. What are we calling it these days? Either way, Curtis Holt sure seems to have been invited onto the inside in short order!
Added:
Laurel wants Thea's help in convincing Merlyn to resurrect Sara, but it turns out it's not Malcom she needs to convince.
Added:
It looks like Oliver spotted the bad guy. Or A bad guy, anyway. That's not just any finger point, right? That's THE finger point, the one that calls in the reserves, that makes all the other good guys come running in for an assist. Surely. Right?
Added:
In case you didn't notice previously, there was a bit of a security breach in Jessica Danforth's team as Lonnie Calvert (ANARKY!) got a role front and center on her protection detail! Oh no!!! Someone was not doing an adequate background check.
Added:
There aren't many members of the family left, and I suppose they are not technically Queens, since Thea's father is a Merlyn, but together they stand vowing to protect Jessica Danforth throughout her candidacy as mayor of Star City. They're good people!
Added:
Jessica Danforth (guest star Jeri Ryan) announces she's running for mayor of Star City, scaring the pants off of Oliver and Thea, as she's a dear friend. Nobody in their right mind would want a friend running for mayor when the last three people who had the job were killed!
