The devious program's writers' room reconvened at the end of May, but the rest of the crew is only just starting to trickle back in. For Jill Ohanneson, costume designer, the season began on June 22.

"Excited to start back on #Revenge S4!! and can't wait to see where the amazing writers will take us this year!!!" Ohanneson tweeted on Monday.

Why Hasn't Emily Killed Victoria On 'Revenge'? Each Plays A Role In Their Own Unhappiness

Although Ohanneson is currently getting updated on the well-kept secrets of season 4, such as who will be donning a prison uniform and whether or not she will need to whip up clothes for any more miraculous resurrections, the costumer is still fuzzy on the actual premiere date.

"We will air sometime mid to end of Sept.," was all Ohanneson could disclose about ABC's schedule for season 4.

To meet that deadline, the Emily VanCamp fronted series will begin filming in July.

When the long summer hiatus finally comes to an end, Emily (VanCamp) will have to deal with the death of Aiden (Barry Sloane) and the return of her father while Victoria Grayson (Madeleine Stowe) will try to find her way out of the mental hospital and Jack Porter (Nick Wechsler) will have to attempt to keep himself out of prison.
