Eve Polastri works for a department of MI5 that provides diplomatic protection for visitors to the UK, under her boss Bill Pargrave (David Haig).

She is called in to a meeting attended by her supervisor Frank Haleton (Darren Boyd), and Carolyn Martens (Fiona Shaw), head of the Russian desk at MI6.

The sole witness is the politician's Polish girlfriend Kasia (Edyta Budnik), who fled to London, and Eve's department is assigned with protecting her.

She returns to the hospital room to find the nurse and the two guarding police officers dead and Kasia dying, whom she tries in vain to save.

For the assassination in Tuscany, Villanelle arrives to kill Cesare Greco and is caught out by what actress Jodie Comer calls a surprise party.

Writer Phoebe Waller-Bridge said she liked the idea of Villanelle having to improvise, after only turning up with her hairpin needle, to secretly kill him whilst surrounded by people.

Executive producer Sally Woodward-Gentle said it was difficult to make the murder feel real, using camera angles and off-screen space to achieve this.

[6] Jo Berry of Digital Spy refers to the same two moments when she describes how "Waller-Bridge's skill at mixing drama with wry humour is on display throughout the first episode".

[7] Comparatively, Inkoo Kang of Vulture refers to the slightly later moment of Eve asking Elena for her croissant as being when she "reveals her greatness".
