I thought, I'd make it different then the movie. Thorin killed the first one...but Yavanna killed the second one, that you left at the end of the Post. I had Tauriel be on Yavanna's side of the river. There were two orcs mentioned, one that Thorin killed...the second one was when Legolas was staring at Yavanna.

Might make Legolas bit nicer towards her. Or at least, eventually.
