Helena and Yasmine make introductions. She demands that Yasemin stop supplying guns to the O’Shanlins in Metropolis and switch to the Sigiorello family in Gotham City.
On a side note, Chuck Dixon wrote a story where Batman once assisted Huntress with a Balkan terrorist group that she studied relentlessly, could even pick up their dialect. At the minimal, Helena should be able to introduce herself to Yasemin with more confidence. As a young child, she was inundated with tutors. She also spent 3 or 4 years at a Swiss boarding school. That knowledge alone means it’s safe to assume she’d be fluent in German and French. These, along with Italian, are the official languages of the country.
One of the appeals of Swiss boarding schools is they offer intensive studies in languages where fluency in more than one is highly encouraged and attained. After this, Helena went to University where surely foreign language is a requisite. Helena has been shown, not only by Chuck Dixon, but Greg Rucka, John Moore, and other writers, in the past to thoroughly study the culture and geography of the destinations she’s going. From her inception, she’s been an intelligent, high-functioning character, and that aspect should continued in her home book.
