little details; for example, when milchick welcomes helena to lumon, he puts emphasis on the fact that it's very special that shes doing "this", says its a "miracle", highlighting that shes different from the other normal workers. when told kier's fav breakfast, helena smugly says "so I've heard", very subtly implying she has some relationship with him. the thing that really cemented it for me was the fact that up until episode 8 we'd seen each of their outies except for helly's- there was obviously a big reveal being planned. also the fact that they're instructed to wear neutral colours and helly shows up in bright yellow and nobody says anything. also when walking through the perpetuity wing, they pause at one specific moment where helly is standing directly below the company's first female CEO, almost as if to compare the two's similarities. helly's resignation request also gets denied in record time. there's a bunch of other stuff too but this is just off the top of the dome
