What does quien tu va a cuidar mean in English?

There's an issue with this sentence. The second person familiar "Tu" (you) does not correspond with the second person formal "usted" (you) conjugation of the verb "ir" (to go). Either you mean to say, "Quien tu vas a cuidar?" (Who are you going to take care of?) –or– "Quien te va a cuidar?" (Who is going to take care of you?) Those are the translations for whatever your original sentence meant.
