I can't really comment on Shina anymore because I haven't seen her for over a year, not for lack of trying on my part. We have our own issues between us which I don't even understand, but I digress.
For Jasmine and Lana, I didn't know anything about them so in my mind they were TOFFTs that didn't work out. I saw Lana on the first weekend that Seduction airport opened. I thought they were hot, especially Lana, but it takes more than hots for me.
To be fair to Harley, she usually doesn't work at night, and the times I saw her were late at night on her rare night shifts, so maybe it was just past her bedtime and she phones it in that late.
