Those are just suggested solutions to a problem that I see: the scene where Siri comes to Hallendren loses its impact for two reasons:
1) We've already seen Hallendren, so while Siri is experiencing it for the first time, the rest of us are already 'been there, done that' and we don't really experience the dramatic reveal that we're supposed to.
2) We haven't seen enough of Bevalis to contrast. we know that Siri has been living in this drab world all her life, dreaming of something better, but the rest of us have colors aplenty, and we don't see the experience the way she does. Give us at least another chapter is Bevalis. Soaking in a warm bath just makes the bucket of ice water seem that much colder.
The best comparison I can draw is the movie 'the wizard of OZ'
the first part of the movie is all in black&white, and then it switches to color when she comes to OZ. now, while the real world isn't quite as drab as dorothy's, the visual message that we get when we go from shades of grey to the beautiful land of OZ matches exactly to what dorothy's experiencing: a strange and wonderful new land.
Now, if we had spent the first five minutes of the movie with the scarecrow, and then switched to doroth's story, the scene where The house lands, and dorothy sets her eyes on OZ loses its impact because we've already seen it. Dorothy might be stunned by this new world, but the rest of us have already been here, and while dorothy is left gasping, the audience would just be waiting for her to get over it and move on, instead of gasping alongside her.
Take it as you wish, but I think that giving us a sneak peek of Hallendren through Vasher's eyes makes Siri's entrance a wasted scene.
