I don't think that was in the script at the beginning. Not at all. We discussed at length with [screenwriter Justin Kuritzkes] the concept that the [love] triangle needs to flesh out the possibility that all the corners touch - that if you're jealous of someone, you're not jealous of your partner, you're jealous also not to be picked by the rival.
You want to be the object of the affection of the rival, so you're jealous of not being part of it as much as you are jealous of your partner being chosen.
