Hope and Fear

It's fitting that we end the fourth season with a episode focused on Seven (with just a hint of Borg as well), just as we started it. Voyager finds someone who can apparently decrypt the message sent by the Federation (4x14: Message in a Bottle). The message has good news, the Federation has sent a ship to take the crew home! All the good news sends Captain Janeway's instincts on high alert. Is all this news too good to be true? Is this a trap of some sort?
