We have not seen the last of Rose on The Vampire Diaries.
Granted, when Elijah showed up on "The Sacrifice," this character exited the scene faster than Katherine's shirt comes off in this promo. But TV Guide confirms this character will return - and goes on to detail exactly how...
Look for Rose to appear again when Damon and Stefan require help with a "mysterious mission."
This trio will visit a vampire know-it-all who is happy to hand over the information Damon and Stefan seek... in exchange for a day-walking ring. Cue the ominous music.
