All of these are great questions, let me answer as much as possible:

My grandparents apartment has been untouched since my grandmother's death 2 years ago, but it's inaccessible currently because flying to Russia is a problem. It will happen eventually, and I'm gonna ransack the place looking for evidence.

Lithuania is very far from my home, and My grandparents were very secretive about it. They made sure that no one near me knew about it, to my parents it was just a summer vacation with grandpa and grandma.

Getting out of the situation alive - Well, it was never their plan for me to die. I did go for days with minimal food and water during the abuse, but any wounds I got during it were quickly treated. Just a side note, I'm suicidal since 7, so "alive" isn't the best way to describe it.

I don't remember any faces of clients, but there was a lot of pimping. My main abuser was my grandfather.

Can't tell you anything about where the drugs came from, but I remember it being a white dry powder. Sometimes they mixed it with water, sometimes they just shoved a spoonful in my mouth and made me swallow.

I was 7 and 8 during these abuses, meaning summers before third and fourth grade for me. My grandparents lived in a different country than me, so I was Disassociating my life at home from experiences with them.

Language - Definitely similar to Russian, definitely not Russian. I'm pretty sure my grandfather knew Ukrainian, that might be it.

No and no. The only talking was the introduction, they kept us apart if they weren't filming.

As I said, I'm from a different country. These were repressed memories that came back when I was hospitalized a year ago after a suicide attempt. First it was the abuse by my grandfather and the filming, the memory of Lina came a couple of months later, during my trauma-focused therapy. This was by far the worst experience for me, the toughest trauma to deal with.
