Lonnie is a guest character on Season 2 of WB sci-fi series Roswell. She is portrayed by Katherine Heigl.


Lonnie is the other hybrid of Vilandra, growing up in the subway system of New York City with Zan, Ava and Rath. Contrary to Isabel, Lonnie exhibits no moral qualms over her actions, but steals and plots a way for herself to return to Kivar at all costs – including murdering her own brother.
