Bernard is Delia's agent and has been "consistently losing money on her work for years".
Bernard, Grace and Beryl were invited to the dinner with Delia, Charles, Otho & Lydia, until they were shockingly surprise by the monster hands. Soon, Lydia thinks, the ghosts, Adam & Barbara, refused to come down, because they might try to scare them away. Thus, Bernard, Grace and Beryl ended up leaving the Deetz's house.
It is unknown whether or not Bernard appeared in the animated series.
