Profile has the look and feel of some of the EE/Romanian ones I have seen. Whoever wrote it is either illiterate or English isn't their first language as it keeps flipping from 1st to 3rd person. I would not be at all surprised if its a bait and switch job. Have you spoken to her and heard a voice ??
Lets put it another way if it were me I would be booking 1/2 an hour and if she's OK extend it further. If she's not the girl in the pictures walking would be a reasonable thing to do. Saying all that if she is legitimate OMFG she does look fit.
