Should she glow?

[Lalaith]

So, Tauriel´s glow of healing...did it make any sense?

I´m assuming that the idea for the glow came from this:

for those who have dwelt in the Blessed Realm live at once in both worlds, and against both the Seen and the Unseen they have great power.’

'I thought that I saw a white figure that shone and did not grow dim like the others. Was that Glorfindel then?'

'Yes, you saw him for a moment as he is upon the other side: one of the mighty of the Firstborn. He is an Elf-lord of a house of princes.”

But Tauriel was just a lowly Silvan elf. She She´d not been to the Blessed Realm - she may even have been Avari. Did she have any kind of right to glow?
