I THINK there is a lot of history with these 2 people (based on some comments I read elsewhere), and I think his intentions to help her were 100% pure of heart. I think they worked on this plan for a while. My guess is that SP's abuser had a pattern to his behavior-she knew when he would be coming into her room and so BDR told her to get proof and she then sent the proof to someone just in case something happened to her phones or accounts. Sometimes, you have to be your own hero and sometimes you need a sidekick to help with the plans, esp when you are only 14! The system we have to help people in this situation isn't great. we all know this. These 2 (perhaps 3 if his mother was aware of the plan ahead of time) did what needed to be done!
