The next day, Kaidan and Rahna were on the queue for water rations at meal break and discussing the events of the previous night. It had been at least half a year since both of them talked to their families as outside communication was prohibited, and Kaidan mused the reason for BAaT's distance from Earth was to prevent biotics like them from getting beat up by more normal folk. The two developed a close bond during their stay at 'Brain Camp' so when one of their mutual friends arrived bearing news about a transmitter for sending messages to Earth both of them went to check it out, reminiscing all the while.
A teenaged Kaidan Alenko was mulling over Jump Zero's isolation from the rest of the Sol system when his friend Rahna came up to him one day in 2168.
