It's been a while since I've read the series, and I've only read up to book 35, but I'm wondering why can't they just kidnap tom and chapman for 3 days and free them? Also, why can't tobias morph a human for more than 2 hours and then use the blue box again to re-acquire morphing ability?
I have a feeling they're stupid questions and I'm missing something obvious here, but then again it's been about 2 years so... ;P
