Once Upon a Time books Tony Perez for 100th episode

(ABC)

Once Upon a Time appears to be gearing up for one big family reunion in the 100th episode.

EW has learned exclusively that Tony Perez will reprise his role as Regina’s (Lana Parrilla) father, Prince Henry, in the landmark hour.

Details are, of course, being kept under wraps, but considering Hook (Colin O’Donoghue) just brought back a slew of Dark Ones from the Underworld, that should give you a hint as to what’s coming up. Plus: With Barbara Hershey also slated to return, Regina’s parental issues should be out in full force.

The doting father of Regina, Henry first appeared early in season 1, where we learned that Regina actually ripped his heart out to enact the Dark Curse.

Perez joins previously announced familiar faces returning for the 100th, including Hershey, Giancarlo Esposito and Robbie Kay. Victoria Smurfit will also reprise her role as Cruella de Vil, fittingly, in the 101st episode.

Once Upon a Time airs Sundays at 8 p.m. ET.
