Good idea, or tired out cliche?

Recently, I managed to write a new scene for my book Patria, which is my story based off of Les Miserables by Victor Hugo. I now have another new idea for a scene, but I'm not entirely sure it would get a really good response, because it is used a bit in literature.

This new idea would take place shortly after the last scene I wrote, which involved Patria getting into a fight with her mother, and Patria leaving the house in a panic, right into Enjolras' arms. On top of Patria being very upset and frightened, it is raining very hard, and she does not have a hat or a shawl. The following conversation results in Enjolras inviting Patria to stay in his very large uptown home until things cool off at home for her. Now please don't get any ideas; my book is entirely clean. Patria accepts the invitation, and they head to his home.

Now we arrive at the scene in question. This idea I kind of took from Pride and Prejudice, but anyway, when they arrive at Enjolras' home, Patria is worn out and chilled. By the morning she is ill. I know this does not happen as much in our time any more, but keep in mind this is the 1830s. Enjolras is very concerned, so stays with her most of the time. For those of you whom I have not explained this to before, Enjolras is in love with Patria, but she has told him not to be, and though she has feelings for him, she is not sure its love. So that night, Patria starts talking in her sleep, begging someone, I'm not sure who yet, not to tell Enjolras that she really is in love with him. She's afraid that if he finds out, he will lose some of his passion for justice which she loves so much in him. Obviously, Enjolras is right there, hearing every word. What happens from there, neither of my characters have informed about yet.

So my question to you is: is this way too corny and cliche? Or is it a really good idea? Please someone help me, no one involved in the books action are informing me of anything, and I am getting really upset with my pseudo writers block.
