Maybe so, since they talked in Kimoto's inner space and he managed to access Garon's memories, so he seems to be aware of things.
Regarding your second question, it's hard to say, but I believe not. They derive from the same body but are independent, having a mental connection rather than a physical one.
We could think of Jin and Kimoto as non-identical twin brothers maybe
Yes kimoto was aware of the rape. It was on purpose(calculated even)
And no it isn't jin's child. That's not how biology and genetic works
Was Kimoto like aware he was raping Garon? Also if Kimoto got Garon pregnant does that mean it’s technically Jin’s child too????
