P. Volkovna

P. Volkovna, (TV: The Lost) also known as P. Volkon, (TV: Co-Owner of a Lonely Heart) was a cleaner who worked at Coal Hill Academy, having previously worked as an accountant in her home country. She was killed by a skin-peeling dragon, as witnessed by Ram Singh. (TV: The Coach with the Dragon Tattoo)

Her initials "Volkon. P." were later added to the Coal Hill School Roll of Honours Board. (TV: Co-Owner of a Lonely Heart) By December, her surname on the board was changed to Volkovna. (TV: The Lost)

Behind the scenes
Though her identity is not directly linked in Co-Owner of a Lonely Heart or in The Lost to The Coach with the Dragon Tattoos cleaner, P. Volkon is the only remaining character who had disappeared from Class first series and was displayed on the Roll of Honours Board through process of elimination. The rest — Williams. K., Chapman. R., Caroll. C., Dawson. T., and Armitage. F. — are clearly named on screen in For Tonight We Might Die and The Coach with the Dragon Tattoo. Thus, the board follows the correct narrative order.
