Doctor Who: Watch Jodie Whittaker Nerd Out Over New TARDIS During Her 'Emotional' Return To Set

The following contains spoilers from the Doctor Who Season 15 finale, now streaming on Disney+.

Since Doctor Who let fly with its timey-wimey Season 15 finale on Saturday, we've heard from exiting lead Ncuti Gatwa, his heir semi-apparent Billie Piper, and showrunner Russell T Davies.

But the true delight is seeing Jodie Whittaker — who popped up as Thirteen during "The Reality War" — first lay eyes on and unabashedly nerd out over the new TARDIS set that succeeded her three-season run on the iconic sci-fi series.

"Oh my God, it's massive!" she remarks, unironically, upon passing through its doorway in the BTS video below. "Beautiful," she deems the set that Gatwa got to call home for two seasons. "Isn't this immense."

Whittaker goes on to say she felt "incredibly hyperactive" upon returning to the series' soundstage in Cardiff, capital of Wales, and grew "incredibly emotional" when she reunited with crew members who worked there during her Season 11-13 run.

Then there is the matter of donning once again Thirteen's trademark Time Lord fit. "I was like a pig in poo," the English actress shares.

"I was a delighted it still fit," she adds with a chuckle, "and delight that I still look class!"

Whittaker's three-minute encore was brought about when Fifteen's mission to fix the 1-degree shift in reality caused by the ending of Conrad and the Ranis' Wish World had ripple effects. "I popped out of my timeline because there's a great big time schism on its way, caused by you," Thirteen explained.

Before Thirteen left, Fifteen said, "I love you, Doctor." Taken aback, in a good way, she noted, "I never say things like that" — and wondered aloud if should express such a thing to her companion Yaz/Yasmin Khan (played by Mandip Gill). But Fifteen assured his predecessor, "She knows."
