Clare Beddor issue

We know that Rhys takes Clare Beddor under the Mountain and presents her as Feyre.

Why didn’t Tamlin or Lucien address it (or have I just missed it). They must know Rhysand is not an idiot, nor is he blind - even if Fayre had told him the fake name, he had seen her. He must have known he was bringing in the wrong girl as Feyre. Tamlin and Lucien must have noticed it too - and I don’t remember it talked about as to why would Rhysand take the fake girl. Did none of them had a moment of deep thinking why would he do that? If he was Amarantha’s loyal whore to the bone, he should have brought in the real Feyre. Even Amarantha was more suspicious than them!

While Feyre suspected Tamlin stayed silent as Clare was tortured to protect the real Feyre, it was Rhys who initiated the scheme - and thus protected Feyre. Yet, people just ignore it.

Thoughts?
