Lexi Carter is Jack Carter's baby sister. Her interests include travel, New Age spirituality, saving the planet, and politics - pretty much the antithesis of her straitlaced brother. She arrives in Eureka on the same day that Nathan Stark and Allison Blake are to be married (I Do Over) and leaves with Duncan (the father of her twins) several months later (It's Not Easy Being Green). Although referenced thereafter, Lexi is not seen again.
