One particular recurring point with Pamela in each of her appearances is that she can never recall the circumstances surrounding her death. It never comes to light, even through sidequests related to her, and is always kept a mystery (with the exception of Atelier Iris: Eternal Mana). Despite the rather dark ambiguity that involves her unknown demise, she has grown accustomed to being a ghost and makes the most of her spectral existence. This is often noted in that she enjoys scaring others as a practical joke and is always in good spirits.
In Atelier Iris, Pamela appears as a ghost who is friends with some of the children of Kavoc.
Pamela can't remember how she died, or where her corpse is, so she wanders around hoping to find it and restore her lost memories. Despite this gloomy mission, she remains upbeat. She enjoys being a ghost and sneaking up on people. She also becomes smitten with Arlin if you talk to her while he's in your party. Despite Arlin's straightforward words of rejection, after an initially dramatic outburst by Pamela where she believed Arlin to be a ghost like her, she becomes her upbeat self again after realizing he's alive, and requests that they go out once he's a ghost, too.
Pamela again appears as shopkeeper in Atelier Totori.
She now has a physical body and has moved to Alanya due to a desire to see the ocean. She sells wares at her own store in the village. Her physical body was a sort of doll created for her by Astrid. In order to help Totori and her friends enter the Liechtein Soehnle, she offers up her ghost body as a sacrifice. Totori is shocked as, up until that point, nobody in the village of Alanya was aware that she was actually a ghost.
Meruru can register items at Pamela's Store. She has abandoned her human body, and has decided to go with her ghost body. She is delighted by the initial scared reactions of the people in the kingdom, as everyone where she lived before has long since grown used to her being a ghost.
She is available as a downloadable character for the Playstation 3 edition, and can be purchased from the Playstation Network. In Atelier Meruru Plus, she is recruitable as a party member after an event in Pamela's shop that will occur at least 30 days after Rorona has become recruitable.
In Trinity Universe, Pamela appears as a ghost who works at an inn on Empyria. She likes to pull pranks on others, with Prinnies being her favorite ones to pull pranks on. She is cheerful, but often sounds like she doesn't have any real opinion. She is an old friend of Violet Platane and a friend to the demon dog king Kanata. She is considered "empty-headed" by Etna, and together with Flonne, the two make up the "Broken Brain Duo".
Pamela is a nun at Kirchen Bell's church and will exchange items for donations. Unknown to Sophie at first, she died a long time ago and is actually a ghost. She knows the citizens of Kirchen Bell very well and is often seen taking care of a group of children.
