I've decided to think outside the box so bear with me.
Why would someone like Jehan tell an apparently "shocking" secret on tv?
Why would she risk confronting Moana at this point?
(as seems to be the case from recent preview)
Haven't taped the show so I can't look back however Jehan striked me as a sensual woman (not so common a trait) yet there hasn't been any real sexual tension between her and Travis.
weird possibility - what if Jehan & Travis know each other. The two returning b-bettes pick her for the romantic date. He isn't going to take his friend on a home visit so the giving of the rose is not an option. She shows up at the ceremony because its time to reveal her role as spy.
Out there, I know but isn't it fun!
ps: that would be the most shocking rose ceremony ever.
