Siobhan Sharpe

Siobhan Sharpe runs Perfect Curve, the PR agency the BBC keeps hiring despite never quite knowing why. She arrives full of energy, jargon and total confidence, dispensing strategy that means nothing and somehow always lands the next contract anyway. She wants to be seen as indispensable, and behaves as though she already is.

Jessica Hynes turns corporate gibberish into something like poetry, riffing on phrases like 'this is not a negative' with total conviction and no self-awareness. The joke isn't that Siobhan is stupid — it's that she's fluent in a language designed to say nothing, and everyone around her is too intimidated to admit they don't understand a word.
