Hey Sarah,
It's good that you don't understand at this point. When I wrote the second chapter it was suppose to be confusing. I mean, let's be honest, walls don't move (lol). But I'll go ahead and tell you what's happening since you've been so direct with your question.
Our third chapter picks up where the first let off. Sesshomaru has entered her cell because he felt her fading (he thought she was dying, escaping him and his punishment. But she was really dropping into the spiritual center of the earth -it's her gift-)
He deals her a lethal blow and is about to finish it when he feels it. Somehow they are bound. He doesn't understand how as of yet, so there should be some confusion here as well, but that is what has happened.
The fourth chapter is going to delve deeper into what has happened to kagome, but from sesshomaru's POV.
In the second chapter she thinks she has woken up in her cell again, but that isn't the case.-as you already have figured out-
Keep in mind she is a time traveler and a spiritual connector. When Sesshomaru pulled her from her death like trance, her connection to the stones was too deep for her to come out of it. So the connection was transferred to Sesshomaru (imitating a bond). They are bound and she has fallen into his past for a second, re-living a horrible memory.
It's a lot, and it will get confusing. Hopefully this pulled a few knots loose on your confusion. I like to let my readers guess what is happening, make their own assumptions. And then blow their mind with what is happening.
I'm also thinking of moving chapter 2 to chapter three so the flow is better.
Less questions that way.
Anyway! Thank you so much for your review! Happy reading!
Mandy
