While "Arrow" season 2 goes on its winter hiatus, spoilers continue to surface regarding the future of the CW hit series.

Regarding Alex Kingston as Dinah Lance, the character will return in "Arrow" season 2 episode 14.

“Episode 14 is probably the most 'Brothers & Sisters' episode we’ve done,” said showrunner Andrew Kerisberg. “Everyone in the Lance family has big secrets and it’s all going to get blown wide open, but in a good way.”

And one thing "Arrow" season 2 will likely address is blossoming romance between Oliver and Felicity, otherwise known as "Olicity."

"Felicity may be a fling, I have no idea," said Katie Cassidy, who plays Laurel Lance on the show and Oliver's first love interest.

"But you know, bring it Felicity. Laurel has got this!"

And another interesting tidbit that has risen recently is the assertion that Batman and the Gotham City mythology may be brought into "Arrow" season 2 for a future episode.

It began when some IMDB users claimed they saw an episode summary for "Arrow" season 2 episode 21 that read, "Oliver gets a business opportunity from a famous billionaire from the neighboring Gotham City."

Despite these tantalizing spoilers, Stephen Amell aka Oliver has firmly quashed the rumor with a simple "no."

It would be unlikely that an episode summary has been leaked so far in advance, but if Batman aka Bruce Wayne is indeed coming to "Arrow" season 2, no doubt spoilers will soon arrive regarding the casting of such an iconic figure.

Would you want Batman to cameo on "Arrow?"
