Did LV ask Snape why he was protecting Harry

Hi,

Have recently restarted from SS/PS, and the above question came to my
mind.

In HBP, Snape is clear that LV has questioned him, after Bella asks
him a number of questions at Spinners end. However, the above question
would not be a question that Bella would probably ask.

She did ask - And why, Snape, is Harry Potter still alive, when you
have had him at your mercy for five years? - but she would not know
that Snape had atleast on one occasion protected Harry.

LV however would know that, simply because he was possessing Quirrell,
and Snape was dueling Quirrell to prevent Harry from falling off the
broom in the Quidditch match.

Even if LV was not possessing Quirrell at that time (and IMO he was),
he surely was there in front of the Mirror of Erised when Quirrell
told Harry that Snape was muttering counter-curses to save Harry.

So the question again - did LV ever ask Snape why he was trying to
actively save Harry, and if so, what do you think Snape's response was?

Cyril, hoping that this has not been covered earlier, because I think
it would be fun to think of the possible answers that Snape would have
provided.
