The Doctor nods - time and therefore Nexus threads are - timey-whimy. "Seems he didn't escape. Still trying to work out how he's alive here, yet knows he died in his world."

Sure the Doctor can pull it off, but he's a time traveller, so...

"It used to have a lot of natives about. Might be difficult to tell them apart from those who've been here a long time now. But they used to wander around the flats and shops."

Those were the days when the Nexus was pretty much the plaza and nothing else. The Doctor sighs he misses the 'good old days' when the Nexus was smaller, but simpler. 🌱
