Annie, to put it bluntly, was in a temporary state of shock. In all her times of spending time with Jacen she had seen a lot of emotions ranging from absolutely excited to wanting to suck her blood (it was Halloween and you didn't question these sorts of things on October 31st). Crying had never been something she was used to with males either, though Alfie could when he wanted to make her feel extremely guilty. This just made her feel sad and all the more confused as to what she had to do with this that had caused Josie to go this entirely postal and send her twin to leaving the house. Annie and Lexie fought and occasionally she had gone off to Penny's for the night, but nothing to this magnitude.
She went over slowly and sat down next to him on the booth bench and just put her arms around Jacen loosely at first. If he wanted to push her away he was still free to do so but she's give him a moment to decide before hugging him any tighter and just letting him get it all out. Didn't every girl know how nice it was sometimes just to have a good cry?
