Oliver is technically still married to Nyssa (Katrina Law), even though he was undercover. How does that dynamic play into the finale?
It actually prompts two of my favorite lines in the episode. Suffice it to say, Felicity has some nuggets to share. Either one is really my biggest swing into trying to get into the quotes page in Entertainment Weekly. [Laughs] I’m taking my best shot here.

This made laugh, because I’ve been wondering lately when I’m going to see the return of Felicity Smoak on the entertainmentweekly quotes page (she’s made one appearance with a quote from the episode “Going Rogue” of “The Flash”). Funny that Mark thinks about the quotes page, too, and Felicity Smoak is his best bet, of course ;)
