I don't recall them ever embalming anyone during the course of the show. And now come to think of it, I don't remember them ever holding Wakes either, except for the time when Grandmamama died and they actually held a Wake for her in Collinwood, which is how they held Wakes for the deceased way back when.
It seemed though as soon as someone died they were immediately thrown into the ground with a tombstone all made out as if it were expecting them.
Could you imagine all the hard work Dr.Lang would have had if they did embalm bodies??
