wikipedia and IMDB both say Lucy Saxon is returning in episode 7 "A good man goes to war". I know that both these sites can be editied by anyone so this could be completely untrue but does anyone know if this is true or not??

Unless Wikipedia hasn't got a footnote next to it, it's a rumour someone has uploaded to confuse people into thinking it's truth.

In other words I wouldn't trust it personally

Wasn't she blown up with the group resurrecting the Master after she threw something into the potion?
