The episode is a bit confusing to begin with, but by the end of the episode everything makes sense. The episodes switches to flash backs and present day. And the flash backs help make the present day more understandable.
The episode starts with Max and Liz in Utah, holding up a convenience store - how uncharacteristic! And of coarse, they are soon arrested. The reason for their wild streak soon becomes apparent: Max is after the space ship that crashed in 1947. He wants to use it to go home to save his son. As the episode progresses we learn a couple of interesting things: Max and Liz are a couple again, Isabel is dating an attorney who just happens to be her fathers assistant and who is 8 years older than her, and Michael takes a job as a security guard working very strange hours. Of coarse Max and Liz can not stay in jail for very long, this show is called Roswell not Prison Break! Isabel and Michael look great, and more mature with their new hair styles.
This is a great episode, and sets the standard for the rest of the season. What a great episode it was indeed.
