One thing I've been thinking since I last re-read the end of fairy dance, I wonder how they will adapt the Kirito/Asuna scene in the hospital at the end. Will we get a shriveled -up Asuna like we did with Kirito?(probably not, judging from how she looked in ep.15).
One of the things that really struck a chord with me was how Kirito hears Asuna's real voice for the first time, which for me kinda brings the whole thing full-circle, and really drove home the point that their ordeal had finally come to an end(for now anyway
). The fact that Asuna was so frail in that scene only made it more touching.
Unfortunately I doubt either of those will really be in the anime version, the voice bit is simply practicality, they' can't simply swap the VA of the main heroine out of nowhere, and I doubt they're going to really show a sickly Asuna, oh well.
