It's not really news to anyone who has been involved with the weyrlings since the hatching that Vivian was a little bit on the broken side. Although she has been keeping up with the care of her dragon Kelioth, she has been more than a touch vacant since the hatching, the usual immaculate care she always took of her appearance was lacking and the spark that everyone knew and loved/hated was gone.
Well at least it was, until one snowy afternoon she came back into the barracks, Kelioth babbling on to all who would listen about how nice Inimeth was as he flew away, presumably with his rider, D'son. Whatever it was that was discussed, the spark was back, Vivian has come to terms with her life plans being shattered, though this probably means that she is forming new plans and everyone better beware.
