Update: Hayley will appear in Season 4, Episode 16, "Bring It On." See the synopsis here.

Mystic Falls has a rapidly declining werewolf population, but is that about to change? Based on a tweet from Phoebe Tonkin, we could be seeing Hayley once again.

“ATL,” wrote Phoebe, along with a map of Atlanta on her Instagram. It certainly seems like she’s headed off to do some filming!

Phoebe has already been cast on the The Vampire Diaries spin-off, The Originals. Rumor has it the pilot will begin filming March 6. Is Phoebes heading down a bit early, or will we see her in an upcoming TVD episode? Normally we'd think she'd want to avoid Klaus (Joseph Morgan), but the werewolf will probably be seeing plenty of him in New Orleans.

Maybe she’s bringing Caroline (Candice Accola) a message from Tyler (Michael Trevino)?
