A woman like that, aside from her looks, has nothing to offer. She probably heard that the Scott family studies Mechanical Techniques and wanted to impress Ernesto Scott, so she pretended to understand these design drawings.

Having served the Scott family for many years, although there were unhappy moments, being so bluntly rebuked by an illegitimate daughter was something she found hard to accept.
