I think something dodgy went on with Emily because she started dating that bloke that was friends with Alex, then within 2 weeks they were engaged. Shortly after that, she disappeared off tiktok, Instagram, she was never in any of Sam's pics or videos anymore. No one thought anything of it at the time because they just assumed she was in that honeymoon phase where you forget about your friends for a bit (it happens!). Then maybe 6 months later, Sam posted a story on Instagram which said something like "It looks like I've been removed off your followers list and can't contact you, please get in touch if you can, we miss you". I'm paraphrasing but that's roughly what it said. Had to be aimed at emily surely. Anyway It's very strange and kind of worrying.
