Kai and Juliette met the night Juliette was kidnapped from her grandparents, and was forced to kill a man. Kai provided emotional support to the young Juliette, and the two bonded rather easily. Together they faced down the gang, and ended up leaving the gang and making it to the Alliance. Together they went through N7 training, and eventually ended up on the Normandy together. Juliette has always let Kai take the lead; however, after learning about Kai's death at the hands of the Collector she became merc, and rejoined the Normandy during Kai's mission to take down the Collector's. The two of them work exceedinly well together, even if Juliette seems like she's causing trouble for Kai. Kai is always the first person she looks to for comfort, and Kai is always the first person she thinks of protecting.
