I see the problem on how the things are done
She lives with calvin and have sex with him 5-6-7 times a day... it's not the situation of having a color friend and from time to time meet to have sex. It's pretty easy on this situation we say.. oh no problem just friends but it's more then that
If that thing of the passport means what we think.. It's a principle for Calvin to assume (even if not directly, but unconsciously ) that she wants him to be with her more then before.. things are "growing" .. not just the guy from the couch
She need to "protects" him from this kind of situation.. Because in relationship or not.. this will hurt and they know that.. especially doing like this.. And especially since both know vh, both know the archive and both visit CC. If she wants to bring him to this "parties" my idea is or put him together on the moment or decide on that night just meeting with friends and if she wants to have something more don't need to bring him (especially when juliet seems to be in another wave)
