To me it just seems irresponsible. The BBC isn't supposed to be a money making operation anyway. That said, you'd expect them to take the responsible approach and confirm/deny and not be misleading in the process. That's *not* asking too much.
I believe Watling and Hines. It's possible some things got scrunched together. Like, maybe Watling learned about the episodes prior to June but didn't see it until after. There was a delay between when she learned about them and when she saw the screen.
