Baba Yaga's smile grew a little, and there was no hiding her relief when he accepted it. He could feel it after all. Her fingers tightened on his, and for just a brief moment, she touched her right hand to their clasped ones. It was possibly cruel, or just a way to help him remember they were very much there, because the back of her silver engagement ring pressed into his skin for long enough to sting.
"We are here to be joined." She looked at the only person present she might have reason to fear. Yes, Hannibal could probably find a way to end her life. Same as the vampires. But, Jesse Custer could decide to send her away, make it so that she did not exist, or worse, he could make her human, useless, pointless, nothing. She knew without delving too deeply into his power, into his being, that he could do much more than any of the others present. Perhaps that was why she wanted him here. He was a witness, and his words counted.
"Make the most of it. Who knows when you'll get another chance like this." It was only a hint of snark, but the wink and the smile while a little flirty said she was quite possibly honored to have him here. Her eyes didn't stay on the preacher man for long though; no, she truly did only have eyes for the man beside her. She allowed herself this moment of forgetting this was a liability in so many ways, and she let herself seem more a fairy tale princess than a supporting character in a story.
