For example, Ana is Señora Ana most of the time, because the narration is in English. If she's part of a whole sentence in dialogue in Spanish, she is la señora Ana. What's kicking my butt is the point of view character's habit of thinking of her as la Señora. Is Señora capitalized or no?
Likewise, Captain Muir Is Capitán When addressed directly, but should the point of view character think of him as El Capitán, el Capitán, or el capitán?
Thanks in advance if you can help.
ETA: I don't need help with the English--it was provided only as an example. If you've already commented on it, I apologize for taking up your time.
