History
Marielle was born in Andorra la Vella, Andorra, to a French mother and English father. Her father had a Russian heritage, however Marielle herself does not identify as Russian. She moved to the UK aged 16 as she wanted to pursue an education at the fabled Oxford University. There, she met Charlie Tindall (née Bradshaw) and Lorelei Stalder, who were completing their graduation. Marielle quickly topped the class, however was generally misunderstood and pushed under the bus as she was the "foreign student". Lorelei sympathised as she is Swiss, and urged Marielle to ask the two of them questions if she had any. Marielle used both Lorelei and Charlie to gain top-notch grades as well as popularity, as she was known as the girl who was friends with two amazing students. When she finally graduated, she purposely dropped contact with the two girls and ignored their repetative methods of contact. She replaces Lorelei Stalder in Season 10 as the new head of the biochemistry sector at MI6, however acts coldly towards ex-friend Charlie.
