>>2680660I don't think the author is too far off, it definitely represents escapism to a degree. It's seems to be another way of telling what Lain we're seeing. Most of the time we see Lain wearing it she is around her family, or confused. We don't see confident wired Lain or the knight's Lain ever wearing it. Think about Layer 01, when Lain asks her father for a new Navi she is shy and in the bear suit. Later in the series when she gives her "The border between the two isn't so clear" speech, again to her father, she is not wearing the bear suit.
Then we she is fully realized as a Goddess, and to another extent an individual, she is told she no longer needs it.
Lain is fully of nice visual and audial clues like that.
