Even if you are not in Bella's path, the secret will still be impactful. Of course if you don't the scene with Bella in the library, the build up to this is a little less dramatic, but still dramatic nevertheless.

JADE: Oh Bella why do you have a nusery
Bella: nows not the time to talk about it as a college freshen bleeds all over my floor
JILL: Oh that's why you were at my group session
Bella: I said I don't want to talk about it
Or similar shit...
