Here's my boy Cairo and his boss/mom(?) Giza.
Within the context of the story most the basis of Cairo's identity (birthday, country of origin, specific ethnicity, parentage/familial connections, birth name) have been withheld since childhood so that he can better adapt as an undercover agent. It's implied that Giza may have also experienced this growing up, but either way she's not letting anyone know anything about who she really is. So Cairo never learns his specific ethnicity, but later in the story he learns that one of his parents is latine (although I'm not sure how much he identifies himself as latino after this point, having not been raised in that culture). So, mixed/displaced/reconnecting(?).
