Victor is Dominican, and all Dominicans are Hispanic/Spanish. Oh! Another thing, the majority of people in DR are of African, European and Tahino descent. There was very little segregation in the Spanish colonies, and people eventually intermixed (as opposed to the US,) thus creating the mulatos (mix of Africans, Europeans and Tahinos) or mestizos (Tahinos/Mayans/Aztecs/etc. with Europeans).
But other than that, and specially when he opens his mouth and talks, after the first word... you can tell Victor is Dominican (hence Spanish) to the core.
