Erilina had ran in front of Kol to protect him from Klaus's attack, then suddenly Erilina collapsed on the floor with Kol and Klaus looking down at her hoping she was alright, Kol tried to wake her up but when she didn't wake, he felt her pulse, she was still alive, while Kol was doing that Klaus pulled the wooden stake from her lower right hip hoping that the damage that he had caused to her wasn't that bad, then suddenly out of nowhere Elijah appeared
"what happened?" he asked looking at both of his younger brothers with Finn now standing next to him, Finn knelt down next to her and checked her pulse just as Kol did, then looked up at Elijah, with a serious looked on his face,
"she is alive, but uncoiniouss and seriously injuried, if we get her to the hospital or giver her some blood she should make it" said Finn with a incredibly serious voice, seemily worried about her and woundering what had happened. Elijah looked at Kol and Klaus and repeat what he said, except this time angery at the two of them for causing an injury to her.
"it was my fault, i aimed for Kol and she jumped in the way to protect him, i could stop myself in time and when i did, it was to late she was already on the floor like this" replied Klaus
when they had got to the bottom of the plot, Kol knelt down and gave Erilina some of his blood to heal the injury that she had sustained and then took her back into her house and upto her bedroom and waited for her to wake up, he wanted to her to wake up so bad the he was going down stairs then coming back up every hour to see if she had awoken, then the next day he went and noticed that she wasn't in her bed, then she walked out of her bathroom with a towel on,
she is awake.
