Two things I can't remember if we found out the answer to
1. When everyone thought Catherine was dead after finding 'her' cœur, coeur in the box, did we ever find out whose cœur, coeur it really was?
2. What happened to Lily? She was all set up to be another villain with a grudge against the Charmings and I don't remember that being resolved - she just kind of disappeared :-/
