Tennant & Smith on Returning for an Episode “It would be nice to do that”
From EW:
David and Matt, you’ve appeared onscreen together at Doctors. What are the chances of us seeing the three of you in an episode at some point?
SMITH: I mean, you’d better ask the Doctor. I don’t know. Jodie?
WHITTAKER: You’re not invited. [Laughs] I mean, when we all get back on set, I’m inviting everyone!
TENNANT: Listen, I had such a great time when I went back to play the Doctor again when Matt was there. It could have been awful! But he was so welcoming and we just had a laugh. And, obviously, I know how difficult Jodie is to work with already, so that would be challenging.
WHITTAKER: [Laughs]
TENNANT: It’s not really up to us to decide. But we all like hanging out together, so it would be nice to do that.
