I find it very hard to believe that Doll is gone, this is probably another situation like Root being "fired" so Doll can hide from Kuz for a bit
Doll has spent all his free time for like a year now either posting on soyjak.blog, the sharty, jannychat, all the splinters, etc. In the jannychat he was always posting links to random splinter threads and posted messages everyday. I really doubt he can just drop it all no matter how scared he is of Kuz, this shit is Logans whole life
If he is truly gone he will be back in a week or 2 when he gets withdrawals from kids calling him daddy
