It could be a mistake, but IMDB is listing Tiger Lily as appearing in 617, 618, and 619. Given that 617 appears to be Snowing-centric and 618 appears to be Zelena-centric, and we don't have a Hook centric in the second half yet, I'm going to take a guess that 619 might be Hook-centric, thus showing off his backstory with Tiger Lily.
