I didn't install any "dialog.tlk" overwriting mods, only Weidu ones - but I seem to have encountered the kind of error that frequently results from overwrites, so I am puzzled.
Having progressed no further in the genie lamp / Kalah plot than receiving the lamp from the girl, I then went around doing other usual quests - and had just popped out of the Slaver Ship when a person named "Hello, again" (yes, in fact, this was in the name slot) appeared and attempted to join my party.
I then had dialogue options that appeared to consist of things that other people would be saying later in the plot. Some screenshots:

Feared I'd never be rid of poor "Hello, again" but finally got this person to leave the party.
Oh, and leaving the lamp behind in the ship and reloading from the save didn't seem to help any.
What on earth was going on?
