If you see her in Shady Sands, then that's what Fixt added. I didn't touch her dialog (didn't really look at her script at all, tbh).
As with all these cut NPCs, they have barely any dialog, and the dialog they have is usually badly written. ... And with the little bits of dialog she has, it is no surprise she was cut from the game in the first place.
Nobody wants to hear or believe it, but the remains of cut content in Fo1 are *very* sparse... there is not much to restore.
/Edit: To add to Agatha ... Based on the dialog bits, I think she was supposed to tell you stories every x time. However, there actually are no stories, and right now it will just advance the time. I guess this would be a nice place for a mini-mod of sorts. Like, if someone would want to write various stories, they could be added in (I won't write any).
Just saying.
