Friend

S1 E2: Waiting at a café for an informant who will advise her who the next Section One target will be, Nikita is recognized by her longtime friend Julie, who knew Nikita before she went undercover with Section One. When the informant sees that Nikita is not alone, he refuses to give Nikita the information. Michael tells Nikita that, because Julie recognized her, Julie must be killed--either by Nikita or someone else. However, what Nikita does not know is that Julie is actually Section One's next target.
