Portrait and Keywords

I got my partner up to 184 Disposition, and I received new keywords from her after talking to her about Private Story. She gave me Laighlinne's Transformation, which is described as "You wondered how she would react if you said you wanted to see Laighlinne in her red hair." Using that keyword on her will give you the next keyword, Laighlinne's Charisma. This is described as, "Laighlinne must have been charismastic when she led her family. You want to learn Laighlinne's Charisma skills." Using this keyword on her will then give you another keyword to use on her, Laighlinne and Sera, described as "You understand it is an uncomfortable subject, but you want to learn a little about Laighlinne's father." But wait, there's more! Using this keyword on her will give you yet another keyword, Laighlinne and Harp, described as "There was a harp in the fleet Laighlinne lead. You should ask Laighlinne, what she thinks of the harp." Using any of the 4 new keywords on her will change her portrait to her red-haired Laighlinne portrait. I can add these later to the Keyword list as well as her responses to each one later.

Do you lose any of the keywords upon use?

Doesn't seem like it.

I've talked to her with those 4 new keywords many times and they're still there.
