I am already wondering how Petra's body (which tends to automatically try to annul anything that might be considered a toxin) might respond to some of Sybil's cooking.  She has to suppress her abilities to get a 'hit' from even caffeine.  ;)<br/><br/>Petra'll be fascinated to meet the non-Norca plant nerd who secured such an important post: there were probably quite a few Norca who'd assumed that hydroponics would be almost entirely their preserve!  And it sounds as if Petra and Sybil have some key interests in common.  :D
