I know you are wanting to not reveal anything about future episodes or future villains; however, you mentioned that you were perhaps planning to place Daleks in much later episodes. I must at the very least ask, how are planning to do that? Since the Time Lords and the Daleks practically wiped each other out in the Doctor Who series, and it doesn't seem that Time Lords nor Daleks exist in this universe. SO, I just wanted to ask if the Daleks would appear like the Doctor appeared or differently?
Doctor Who is well known for it’s twists and plotholes, silly. If we plan to do something, we’ve also planned how to explain it.
