The uke said something like "that reminds me what i said my mother" something like that......

I think so...

Yh he’s said before he’s scared she’s gonna do something to him

I'm suspecting that maybe, that's the secrets we are yet to discover... I hope I'm wrong (￣∇￣")

I took that like a sign that he was raped/sexual abused by his mother at some point in he's childhood ╥﹏╥

I think based on that line we can assume she indeed raped him at one point, and since then he stopped writing his book because his fears had become reality.
