Edouard is the holographic head waiter of the Paris cafe that Picard recreates on the holodeck when memories of Jenice Manheim are stirred up.
Edouard appears in We'll Always Have Paris. After a distress call from Doctor Paul Manheim reminds Picard of the woman he left behind twenty-two years earlier, the captain has the holodeck recreate the Cafe des Artistes in Paris, where he was supposed to meet her.
Edouard greets him at the door, is pleased by his French and shows him to a table with a view of the Eiffel Tower. He treats the captain as a welcome patron of the house.
The cafe scene lets Picard face the moment he avoided as a young man. Later Jenice Manheim uses the same programme to give the two of them the farewell they never had.
