I think JA is highly manipulative & knew what to do to coax TA into sex. There's no way he would have posed for the sex pics & slept with her if she'd just turned up without telling him.She didn't have to threaten him into those poses either as indicated by the picture he took of her bending over showing her lady bits. She's in a vulnerable position in that pose so no way was she threatening him into it. The times she acted like a crazy stalker just turning up he was mad with her. I believe she acted all reasonable, suggested they take the photo shoot (he talked like it was a fantasy of his in text messages) as a final goodbye. She probably got a kick out of that as it was goodbye in more ways than one.
