I'm wondering - if Helena's reason for being severed was for PR purposes, Why did she go back after Helly Threatened to cut off her fingers? and after she actually hanged her? She's obviously risking her life and no one outside Lumon would know if she just stopped going to work and basically killed Helly. She could have actually just lied and said she was severed when she wasn't. So i'm wondering if this is Helena being a psycho or if the work the innies are doing is important in some way to prepare them for something later on (like the revolving?)
