Consider your walk into a.a.t. to be an automatic spoiler warning. Talk about the dangerous and the dark here, and don't be afraid that you've got to protect someone from it. If we trigger, that is our own stuff to deal with, and we will sit with that and try to figure out what is being triggered, why, and how we can deal with it. Rape is rape. Beating is beating.
Multiplicity is multiplicity.
Don't be afraid to be graphic. There is nothing on the net that can hurt me. And, short of physical or sexual abuse or accidents or illness, there is nothing in real life that can hurt me. Unless I let it. Therefore, I am always safe.
