i do remember then and now always seeing river as sort of multiple different versions of the same character? because it's always been so so clear to me that they decided various aspects of her backstory within specific seasons, with no clear overarching template or goals. so for me there's Library River, Season Five River, Season Six River pre-melody reveal, and then everything after that becomes relatively consistent.

that said, seeing her already very quippy and playful and unapologetically Not Listening to anyone but her (because she thinks she's the smartest person in the room, which is one of many reasons why she and the doctor butt heads soooo often), i'm struck by how very much i'd like to chart her this watch in the same way i often chart a certain other somebody. work from the assumption that all of the information we know exists within the river of every episode and see how her behavior reads with that in mind.
