Hi again,
Has anyone discussed the wierd and sudden appearances Tonks makes throughout HBP? 
She's at the burrow when Harry gets there, She just happens to find Harry on the train. 
Then she just happens to show up outside the Three Broomsticks when Harry catches 
Mundungus, and then she just happens to be on the 7th floor corridor outside the room or 
requirement? she said she was there to see DD, but his office was on the other side of the 
castle?!?! 

Do you think she was really stationed at Hogsmeade, or is she Harry's bodyguard? 
I'm also confused as to her Patronus and why it would change and Snape's comments 
regarding her patronus.

Anyone have a theory on all this?
