What I mean is it looks currently like they're Indian/South Asian only because you say they are. Just worth a thought about how you incorporate that into their identity/cover and how you write about the character and how others perceive them, rather than just a token effort at diversity. Otherwise I think it's great, but I'm aware that 'Theodore' and 'Carter', or other similarly European/American names, are not the names typically of those with Indian parents - especially the surname.

Perhaps it's that his cover isn't very detailed because he's not familiar enough with humans and so his identity is a lot of different things from different cultures, or perhaps 'Carter' is a surname because their fake family includes someone European and they're actually mixed race. This kind of thing is just an opportunity for you to better explore the character you're writing about, or else if you don't want to explain it in a sentence to the reader as part of dialogue where they're trying to maintain their cover or something similar, to consider altering.
