Patil Twins Dying

In a post I made earlier this year, I talked about twins dying during the Battle at Hogwarts. Fred Weasley is one of them (obviously). As you might recall, I also remarked on the fact that in Harry Potter and the Deathly Hallows Part 2, all logic points to one of the twins dying.

While reading Deathly Hallows this time around, I noticed a small comment that I had always glanced over before. While running through Hogwarts, Harry notices Pavarti Patil battling a Death Eater. 


Now, one of two conclusions can be drawn from this:


     1. Pavarti is the one seen fighting, so she must be the one who dies.

OR

     2. Padma is no where to be found, so she must be already dead at this point.



I'm going to hazard a guess that Pavarti is the one who dies, but I still haven't found any record regarding this matter, but it's still driving me crazy. 

I have to know which one it is!
