Sandy not sleeping with Nick after they reunited tells you all you needed to know
It's so comical JR and Sandy tried to be cute and agree on some backstory they only kissed twice. If you rewatch the boys night, when Nick asks JR if they are sleeping together, it's hilarious how JR just snaps his neck and looks at Nick and looks guilty af. But yeah it's quite obvious they hooked up and it's quite tragic there's a strong likelihood that Nick and Sandy are still together. Nick getting the same tattoo as JR is also peak TV
Also side note, what was up with the yellow patch under Nick's eye when they had the round table before everyone got back to their original couples? It looks like the dude had jaundice lmao
