A few more thoughts on Patronus change

I've posted on this subject before - fooling around a bit with the 
wishful idea that the real Tonks is absent in HBP and that someone 
else was disguised as the Tonks we met in the book.

I just can't get rid of the thought that Tonks was not Tonks. Mostly 
because I don't buy the idea of the Patronus change.
Why would a patronus change? She's in love with Remus and it doesn't 
work out for her the way she wants and so her Patronus is changing?
Nope - I don't buy it.

Harry is in love with Ginny now - so his Patronus is supposed to 
change because of a change in his feelings? Nah.

If everyone's Patronus is supposed to change with every new state of 
emotional change within the person - then how would anybody recognize 
anyone's Patronus anymore?
It just doesn't seem to fit.

Snape was mocking *Tonks* over her *new weak* Patronus. 
I don't think so. Snape was mocking whomever was disguised as Tonks - 
and Snape knew who that person was.

So - who was it? Or am I just on the very wrong track here?

PS! A little sidenote. Tonks was supposed to patrol Hogsmeade 
but 'she' showed up at Hogwarts on occassions when she was not really 
supposed to be there - and seemed rather distracted by her own being 
there.... another puzzle - another post - maybe.
