I can't imagine Gail on her own in Thailand. It just doesn't fit with the character.
I am a bit uneasy about the Hope storyline. She's always been a bit . . . disturbed, and whilst I'm sure there are children like that, I worry that the fact that her father was a serial killer will give the impression that it is a hereditary predisposition. Maybe it is, for all I know, but I'm not sure that a soap is the best place to deal with issues as complex as that one.
Regardless of Hope, I do think that 10 years old is far too young to be sentenced to 10-12 years in a correctional facility, though. She does need help (or would if she were real), but taking her away from a caring loving family doesn't seem to me to be the best thing for her. Maybe if she were my daughter I'd think differently, though
