As of yesterday, PewDiePie has said several things on how the doll that Marzia bought got missing after they're going to the cinema. A few hours later, he twittered another report that he, and Marzia heard a weird noise outside their bedroom, and he already prepared some salt to fight the haunted doll.
Evidence #1 - Ominous Tweet
"Ipse Suus Venit = He's coming"
Evidence #2 - Hasn't returned to give any reports (something like "The weird noises are nothing") and it's been a day now
- Pray4Pewds and let's investigate this weird occurence together. We will not fall because we're brothers. We will not fall because we have each other's backs.
Any speculations is a welcome.
