I have a Babylock Quest, and I'm trying to figure out what part came out of your machine. There is a flat, 3/4 circle Piece with sort of a "M" shape in the middle that fits into the bobbin case. Is that what came out? If so, it looks like you could carefully put it back. A picture would help a lot! Maybe if I can see exactly what you are referring to, I can help you out.
