HELP!? How does Martha Jones in "Gridlock" know what the Face of Boe said in "New Earth" to the Doctor? She wasn t there, Rose was. Help!!?

I ve seen every episode of Doctor Who multiple times and I just caught this while watching season 3. She says to the Doctor "remember what the Face of Boe said?" And then he recalls what he told him in New Earth, the episode in season 2. Is there an episode kn season 3 where the Doctor tells Martha about the Face of Boe?


I don't remember, but I do remember Martha knows and spent a lot of time with Captain Jack (in Torchwood & the novels/spinoffs).
