S2 episode 1 Helly Theory (devils advocate)

Everybody has the very same thought about Helly after seeing episode 1 but one thing I noticed was that when the whole gang went back to the office she said “wait. What happened to the security cameras?” She was the first one to notice they were gone. Only her innie would know that. Yes it’s possible it’s a red herring to throw the other innies off the scent. It’s possible she also received some coaching to help her with that.
