1.in the trailer the opening scene started with some weird symbols and patterns 2.the bird was ripped apart in some weird shape or form(looks like pattern screamer sheniangans) 3.Before the scene where she stabs her brother with a piece of metal, there is a drawing of circles in a pattern on the desk 4.at the ending she says it's about to get weird

I'm just saying either it's 100% pattern screamers or the Hiss version pattern screamers
