Indic is a linguistic group, you can’t be half Indic the way you can’t be half Iranic but yeah his heritage is mainly south Asian
just to clarify though :
iranic term at the same time does have some meaning . west iranics are definitely similar to each other and related to each other . Kurds , Ossetians , Talysh , Gilakis , Lurs , north Persians without south asian admx etc. . . we do share stuff together and it is similar to Scottish - Irish - Welsh - English etc . even though for some odd reason persians often look different from us Kurds nonetheless
but people like pashtuns and balochs are different from us . even though with pashtuns it also depends . for example the "pashtun north afghanistan " from the G25 database is not that much different from northwest Iranics . but even that sample has a lot less EEF than us and also has 8 % or so AASI which we dont have
but thinking that any muh iranic speaker from eastern Turkey all the way to Pakistan are similar to each other is nonsense .
even Romanians and Portuguese are not exactly the same even though they are both Romance people and both european . for example . so how do people expect us northwest Iranics to be like the southcentral asian people lol
