Jane's joking about not knowing anything about Secret Santa was really all in good fun. She was included and it couldn't be helped if the whole world was Christmasy. So maybe she did show up wearing what could only be described as an ugly Hannukah sweater and hold it down for the home team.

How long had she been standing here? Was the ice in her old fashioned this melted when she came in?
