Knowing her brother plans to later call home, Suki attempts to piggyback onto the signal with a homemade satellite phone. As the group are about to reach the roof of the nearest satellite point they a blocked by a gaping hole. When they are about to swing across CJ kisses Ian, since earlier he had admitted he had never kissed a girl. When they get across they discover Whisper was upgraded from version 119 to Whisper 120.
