Ruby might possibly have been insane. Sam certainly thought she was, and here, the hand of someone who could smite her on her shoulder as they teleported or whatever to a Dublin side street Ruby had to admit that it added up to crazy. Castiel could have killed her, at any moment, so easily and yet he hadn't. She wasn't sure what to do with any of this yet, but he'd contacted her, asking about alcohol. It was an interesting turn of events and she wanted to know why he'd done it.
"Welcome to Dublin" she said looking around. "We're officially in tourist land too but its changed a whole lot since I've been here. We're looking for one of the nicer bars, and we can just sit and...whatever, talk I guess. You can get some pretty nice alcohol in here and celebrate the new year. You'll enjoy it."
Talk. To an angel. Weirdly it didn't feel all that twisted. Ruby wanted his advice. Wanted to ask him why it was she couldn't get past Azazel. Why it still got to her that when Sam insulted him it still bothered her. She finally found the steps leading up to the pub from the cobbled street and nodded to Castiel that this was the place.
