While I would love to support the relationship, Lady Elaine does have a point. From her point of view, a maid from who-know-where getting together with the master she serves is scandalous. It is simply not done according to the social convention.
Lady Elaine also seems reasonable. She didn’t immediately reprimand Ibe after receiving the information from the butler. Only after she saw it with her own eyes did she call for Ibe. She also gave only a light warning and didn’t raise her voice in anger or scold her harshly.
If anyone is to blame, I would say it is Alejandro. His conduct of openly favoring Ibe and acting childish put Ibe in a difficult position. She has to balance between paying attention to her lord, doing her jobs well, and saving her relationships with other maids.
He is somewhat excused though in that he is pretty much a child still. Though he may have grown physically a lot now, mentally he has not caught up. (Or perhaps it is expected, since he is pretty much a teenager, an awkward phase to be). He was not taught how to conduct himself according to his status. He has not experienced the world outside much. He has not learned how hierarchical society works.
I am really anxious about what Alejandro would do. I can’t help but feel that his supposed plan might be too naive
