I think Olivia has more Ti than Ne. I also see Si and Fe in Olivia. What progressed a lot in Girls on a Mission (Also in the original series but more in Girls On A Mission).

I definitely agree with Stephanie and Mia, but I thought that Emma was more of an INFP and Andrea an ENFP, but they're pretty similar
