Vivian is a spanish word, it is the improper tense of vivir which means living. This is more of a criticism, as in the story, words are translated by a sort of magical spell. Vivians name should be translated by this (although the word isn't on Google translate). So, this is kind of a minor plot hole. BTW I learnt about improper tenses in spanish class today.
"Ok deeeeeep breath. Now slowly count to 10........ there you go . I'm sure you'd dominate a boob contest with your godsend anyway so just ignore Melany for calling you "tail tail" . She's just mad she couldn't stand her ground against Caylin on the last contest ." ( )
