- —Chloe Armstrong
Celina was the best friend of Chloe Armstrong. At some point, Chloe and boyfriend Josh broke up; Josh would later start a relationship with Celina, which Chloe resented. When Chloe used the Long-range communication device to visit her mother, she later went to her friends, in McCormack's bocy, and claimed to be "Cousin Liz", not knowing they were actually invited Chloe. When they invited her to see Janelle Monáe, she found out that Josh was seeing Celina. At some point, Chloe and Celina went into a heated argument, before she left Chloe, and continued dancing with Josh. (SGU: "Earth")
