indian as in native american of indian as in from india?
Choudhury (in various spellings) is a very common surname in India. Jasminder is a fairly common Indian given name.
And most Indians today who speak English do so with a British accent, or a mix of British and Indian accents, because of the long history of British presence in India. That probably influenced how I wrote Choudhury's dialogue, which might be what gave the impression of Britishness. But it's Kadohata who's explicitly a Brit.
Of course "British ancestry" can mean a lot of things. Indians, Pakistanis, etc. are the largest nonwhite ethnic population in the United Kingdom.
