Man of Doom

In light of Chester Bennington's death, I've become increasingly concerned for my cosplayer friend, who hasn't even touched social media in a while now. It's no longer just the prop I've been waiting on, it's that aforementioned fact. 

I can always try reaching out to his girlfriend, but she doesn't know about me yet, and so far, absolutely nobody is convinced that I'm close friend with this particular cosplayer. 

What should I do?
