Arrow Season 2 Spoilers: Will anyone else find out Oliver's secret this season?

The CW's Arrow is headed toward its Season 2 finale, and fans have started to wonder what's in store for Oliver Queen (Stephen Amell) and his cohorts. One of the most persistent questions: Will anyone else learn Oliver's secret identity as Green Arrow?

That's the question that executive producer Marc Guggenheim tackles in the "Spoiler Chat" column at E! Online:

"Colin: In desperate need of some spoilers on Arrow! Will anyone else find out Oliver's secret this year? So many people are in the know!
First, let's address this one: how has Det. Lance not caught on yet that his hooded friend is Oliver, who has dated both of his daughters? 'Episode 19 pretty definitively answers that question as far as Lance is concerned and I think that the answer will surprise you,' executive producer Marc Guggenheim teases, adding that a few more people will learn Oliver's secret by the end of season two."

In other Arrow news, the following comes from the "Mega Buzz" column at TV Guide:

"Can't wait for more Deathstroke on Arrow. What can you tease? - Glenda 
Now that Slade's made his intentions known, Oliver will worry that his relationship with Sara is putting her in greater danger. Although they're able to overcome that speed bump for now, the couple could be parting ways (in more ways than one) down the line. 'Where they are right now is not where they will end up by the end of the year,' executive producer Marc Guggenheim teases."

Now, couple that with what Guggenheim told TVLine this week about Oliver and Felicity:

"The spark between the partners will 'keep popping up,' promises EP Marc Guggenheim. 'You haven't seen the last of 'Olicity' moments, for sure. But at the same time, we don't try to cram them in.' As for the Gal Friday herself, the EP teases that we'll learn more about her parents in future episodes, with additional backstory coming in Season 3."
