Bonnie was unaware that she was causing havoc in reality,but in the state she was in,she was reliving everything she had seen in Mystic Falls. Some of it too hard to witness again,especially being trapped in 1994. She didn't want to be in the state she was in. But here she was.
The lights flickering by way of magic was not a surprise to Martha. After traveling with the doctor,there want anything that would not shock her. As she screamed the hairs on Martha's neck stood up. She had never heard such a painful scream in her life. Finding the sedative she needed,she gave it to the girl as Diana spoke.
Then Bonnie heard the voice again. She was not sure who it was,but the voice reminded her of her grandmother and that calmed her. She was a Bennett witch and the strongest in her line. She was feeling all the effects of the pain,guilt and remorse of the past few years. As she drifted to peace,she called out the first name that popped into her mind, "elena... where..are you.. need best friend.." and then she felt sleep take her.
"Elena? Why do I know that name? She's going to be here for a while. She seems to trust you so you are welcome to stay with her as long as you like. Maybe ask around and see if we can figure out who this beauty is. Seems like she has magic in her. Strong natural magic." Martha mused.
