If Dr. Ana Steline had a compromised immune system, how could she work in the child slave labor orphanage? And how did she get all the way to where she was the owner of her own company?
Title.
It seems like quite the jump from removing chips on circuit boards to being this wealthy Wallace subcontractor. And if she had a compromised immune system, how could she even survive at the orphanage? Who care enough about her to get her into (presumably) school and pay for her training/education/startup costs?
