Timeline notes
2009 - indefinite: Maria saves Rosalia from the orphanage fire.
2010 - definite: Rosalia is adopted and her brother enters college.
2012 - definite: Cumberland College events. Indefinite: I imagine Sartre ran off with Rosalia around then, and she thought they were just moving to Mexico so her dad could focus on research while her brother worked on his education. In any case, they did live in Mexico and work on research following the Cumberland College incident.
2015 - definite: Rosalia sends Maria a letter from Mexico.
2018 - definite: Sartre dies in America. Indefinite: my guess is that this is within a few days of Rosalia's death, a week at most.
2020 - definite: events of Trauma Team.
Notes
- I estimate Rosalia at fourteen years old at time of death based on her appearance (both older and younger).
- It states somewhere on the development blog that Trauma Team takes place two years after Under the Knife/Second Opinion and a year before Under the Knife 2 (therefore, 2020). Running this through Google Translate seems to confirm what I've heard. The rest of these dates are based off that.
- Supposedly the Japanese Game Guide says that CR-S01 is twenty-four during Trauma Team, sixteen during the Cumberland College attack, and entered college at the age of fourteen--also stated in-game to be his age at time time of Rosalia's adoption. Unlikely age? Yes. Trauma Team-esque? Yes. (Think Franziska von Karma. Trauma Team basically has the feel of Ace Attorney crossed with medical drama with a dash of slice of life/soap opera what in the world is this description.)
- Other specifics: Maria mentions in Missing Girl that she received her letter from Rosalia five years before the game. CR-S01 states in the same conversation that the Cumberland College attack happened eight years before the game. Demons and Death proves Sartre died two years prior to the game--also presumably soon after Rosalia's time of death, because he was vomiting large amounts of blood at the time he killed her. It is established, however, that he had enough time to store his gun somewhere and get the suit he died in; he was also taking large amounts of antiviral drugs, including one dangerous unapproved one, though this could have occurred even while living with Rosalia.
- After CR-S01 I have no idea if Maria is actually a probable age for somebody who I believe was mentioned to have her doctorate (she states in Mournful Hero that she was fourteen at the time of the fire, so the timeline as I've worked it out has her at twenty-five years old, maybe twenty-six, which means she got the doctorate earlier than usual and possibly not long before Trauma Team; it may not matter for her role as a paramedic as much, though, because doctorates aren't strictly necessary to be one), so the guess on the orphanage fire date is pretty fuzzy. I'd consider dating it earlier, but that would place Rosalia at around four years old at the time and I'm not sure that really works.
- If the assumption that S01 is sixteen during the attack is wrong, this timeline doesn't change much--mostly just the dates of the orphanage fire and Rosalia's adoption, and even then they only have a few years' leeway if you consider Rosalia's age as a limiting factor.
