 Kreuk enjoyed the fourth season because it gave her the chance to stretch her acting abilities with Lana 's storyline involving the spirit of Countess Margaret Isobel <unk> . According to the actress , " That was a lot of fun ; I thought it was funny as well [ … ] It really was wonderful to be able to stretch and play this driven woman who has a goal and is going to reach it , and in the meantime she 's going to be sexy doing it . That was a lot of fun for me because the show [ sometimes ] isn 't realistic so , as actors , we get to play with different types of things . " Kreuk says her strangest moment on the show was playing a vampire in season five 's " Thirst " , an experience she remembers as " uncomfortable " due to the fake blood they covered her in . Kreuk left the series at the end of the seventh season , but appeared in five episodes in season eight as a guest star .
