I kind of remember that too, but explain this, then:


 * DOCTOR: It's happening again.
 * ROSE: What do you mean?
 * DOCTOR: I've seem them before.
 * ROSE: What are they?
 * DOCTOR: Cybermen.

Quickly skipping through the episode, it seems this is the first bit of dialogue between the Doctor and Rose about Cybermen. I'll re-watch the episode fully either today or tomorrow and get back to you.
