VS has done with their old angels (when Adriana had to cancel her China event VS preferred to have Josephine to replace Adri instead of any old angel) so it doesn't make sense any of them getting Adri type of contract also Adriana didn't get this work less get more pay contract for no reason. According to PR and brand awareness researches, their longest serving angel (who has been working for them since before current millenium) is still the most influential model of the brand.
IMO every angel will be in China including mrs Levine for sure but their angel status depends on brand's gain or failure in the Asia market. They are too kind to ask their models to leave but its obvious they are not eager to keep them anymore. I thought its just a process until they had Josephine for China event.
