I cannot even imagine, I'm sure. I believe I've spoken with him briefly, but yes that seems somewhat strange.
Jacen, if it is him then he deserves the repercussions, only when it can be proven, though. As for you believing he is a mistake, that is not your place to judge, it is your twin's decision and she is the one that is the ultimate judge of her situation. You may be angry with her, but she is still your sister.
It is difficult to tell at this exact moment. It would not be out of turn for me to say that it is certainly 'freaking her out'.
