Arrow EP Confirms Connection Between Felicity Smoak and The Calculator

Ever since Calculator was announced as coming on Arrow season four, right around the same time Felicity's "villainous dad" was announced as making an appearance - people have been drawing the obvious conclusion.

"We are very excited about this character. He does have a connection to Felicity," EP Wendy Mericle told EW.com. "We're just really thrilled. Tom Amandes has been amazing in the role and is bringing a lot of kindness and a lot of malice to this character."

So, that's not a confirmation that they're father and daughter, but there's definitely something going on there. We'll find out for sure on February 3's episode, "Unchained," which guest stars Amandes, plus the return of Nyssa al Ghul (Katrina Law) and Roy Harper (Colton Haynes).
