First off, I doubt the Treyburn's have an enemy house. Janette, however, is probably unapproved of in many families... so it could just be the girl herself. And if she got into a thing with some known rebellious boy, that could create the whole Romeo and Juliet effect—without having enemy houses. I feel like that's more realistic (and less cheesy, lol). That's just my own opinion, however.
Also, if she got raped, would she really even sleep with a stranger? I feel like she'd be too traumatized...
A woman playing a woman who is pretending to be a man. Am I the first woman? Lol. XD
And maybe a man... Actually, I can totally imagine this. I mean, first off, Jana makes an attractive dude. So if she dresses that up well, the ladies will totally be ogling her. And Jana would use that to try to get information out. ;) She's sneakyyyy.
