Emil is the other servant of the Everglots. He appears to be the butler or valet, but is also seen doing some light cleaning. He is a large-nosed man who acts just as snooty as his employers -- his nose is constantly in the air. He is usually extremely good at his job and very attentive to his employers -- however, when the dead arrive Upstairs for the wedding of Victor and Emily, he immediately flees, leaving Finis and Maudeline Everglot to fend for themselves.
We never see Emil at Victor and Emily's wedding. But Emil was there. Some of the living went with the undead as they went to the Land of the Dead. Emil may have gone with them.
As a bit of trivia, his name is "Lime" spelled in reverse.
