The Undeclared War continues with its second installment on Channel 4 today – and RadioTimes.com can exclusively reveal a clip from the new episode.

The short preview shows an interaction between veteran GCHQ employee John Yeabsley (Mark Rylance) and genius 21-year-old hacker Saara Parvin (Hannah Khalique-Brown) as the latter attempts to track down a mathematician.

The clip begins with Saara sitting across from the rather pedantic John in the GCHQ canteen and asking him why he’s constantly correcting people’s grammar.

“If we wrote code as sloppily as we write English, it would never run,” is his response. “Some things have to be right.”

He then asks why she’s only eating an apple for her lunch, to which she informs him that she’s Muslim and they don’t have any Halal options – before she asks him for help in finding a “mathematician friend”.

“He isn’t here,” she says. “Can you tell me where they work, the mathematicians? I’m new here.”

“I’ll show you if you like, but I warn you they won’t be very welcoming,” he answers, before asking why she’s laughing at his response.

“They won’t be very welcoming? No different to any other department here then,” she says, but this only prompts him to return to his grammar pedantry.

“No different from any other department. It’s different from, compared with,” he says. You can watch the clip in full below:
