I was just reading the preview for tonight's E4 episode

where Warren & Sienna find the cross bearing the words 'Sienna Blake RIP 3rd January 2017' , and I couldn't help thinking that it was actually put there by Ms. Insane herself, to continue the lie about her having a stalker.

Have you not figured it out yet? She fakes her death on the third of january to make Warren pay for what happened to Nico. I figured that out the day the winter trailer was released.

I hadn't figured it out either

I hadn't thought about it that deeply, but tonight's E4 episode at least proved my original theory correct.
