When Chelsea asked if there was anyone else they could call to tell
about the plane crash, Abe said "I don't want anyone else to know
until we have more details". But don't you think Chelsea would want
to call her mother? Or at least have Nick come to the police station
to be by her side? And what about Sami? Given her temperment, I'm
sure Sami would NOT want to be the last to know her mother and John
were in a plane crash and were missing.
