The roles are defined more by the role-player's internal dialogs, thoughts, and feelings than by behavior. The same transaction can be in or out of the DT. Some examples from true life.
Yesterday, the clothes drier cycle was complete when my W said she was going downstairs to mail a letter. I was reading and asked her to pick up the laundry, since she was going to be close to the laundry room. (We live in an apartment building, and I do most of the laundry.)
I could have whined about being tired, hoping she'd get the laundry because I hooked her Rescuer by acting the Victim. I could have said something about having done the dishes and cooking, hoping to hook her Victim by being a Persecutor. Instead, I made a simple request she was free to accept or reject.
She could have taken my request as burdensome but felt she had no choice but to agree (Victim). She could have seen it as an attempt by me to dump my task onto her and gotten angry (gone into Persecutor). She could have seen herself as doing something that I really couldn't do for myself (Rescuer). Instead, she saw it as the simple request I meant it to be.
If I had hooked her R or V, she would have resented me, and I would have not respected her very much.
I hope this is at least somewhat clear....
