AndrewC: Seems odd behavior for someone who willingly left, as Aric2000 relates.
Seems like perfectly clear English to me. I find it hard to believe that someone who willingly leaves needs to come back disguised. Having no evidence that GSHS came back under disguise, I would tend to reject that she did. Now having evidence of her desire to leave willingly it is even more doubtful that she did attempt reentry. Who would know except the person attempting the reentry and those affirming it?
You miss a lot. I'll drop it, per RWP's suggestion.
