Viveca IS indulgent of people she likes now. The colon (:) introduces a list of unconnected facts about Viveca. 'Indulgent of people she likes' has no connection to the preceding fact, 'grew up ... working class family'.

My guess is number 1. The writing isn't as clear as it could be, but since the next phrase "cries at commercials" is about the girl (not her family), I'd say that all the phrases are about the girl, not her family. Also, the specific punctuation before "grew" and after "family" supports this conclusion, although it's really not a good idea to depend on a punctuation mark to disambiguate a sentence.
