This one is my favourite, and it's from Buzzfeed's Sylvia Obell. We all know that young women on Instagram tend to wear similar outfits, hair styles, and fall into similar aesthetics — Refinery29 literally devoted an episode of its Style Out There series about the Calabasas vibe — so what if someone at this party was cozy with Tristan and she just happened to look like Jordyn? If this is the case, then it would make sense for Jordyn to immediately deny all the rumours (which she hasn't yet), but it also explains why all the sisters still follow her on Instagram, and seem pretty chill about this whole potential betrayal.
