We've said it before and now we have to say it again - Elias' Quantico story line is not quite over.

The lawyer/terrorist/former NAT swan dived out a window in the midseason finale, but he still cropped up in the midseason premiere. Now, thanks to Quantico's unique blend of past and future, Rick Cosnett's character will also appear in the season finale.

Cosnett, who recently defied his Flash death for a turn in "Flash Back", posted a teaser photo on Wednesday.

On Friday, Entertainment Weekly confirmed the actor's return. The exact nature of Elias scene, however, remains unknown. Will he appear in the Academy timeline? Pop up in some more security footage? Or could he find a way into someone's flashback? Viewers will just have to wait and see.

ABC has yet to drop a logline for "Yes," but showrunner Josh Safran teased the finale in the wake of last Sunday's "Soon."

"It's been a whirlwind season, but everything does line up. That's the thing I'm the proudest of," Safran told TV Guide. "Even though the finale's action-packed and exciting and thrilling, it's also very emotional. At the table read, people were very moved."

This week, viewers will start to see the puzzle pieces slot together in "Fast." Not only will Alex Parrish (Priyanka Chopra) meet someone who knows the terrorist endgame, but we will also find out why Shelby (Johanna Braddy) was working with The Voice.

"At the end of the next episode, the very last moments pretty much - not pretty much - tell you directly what the rest of the season is going to be," Safran teased, according to Entertainment Weekly. "From the very end of 19 on, we're pretty much in real time in the New York storyline and the master plan is revealed."
