A point of confusion: when Chase asks Cameron if she ever loved him, Cameron says that she doesn't know. But then she realises that House has corrupted Chase vis-à-vis Dibala's murder. That was the last episode to feature Jennifer Morrison as a mainstay: Morrison left the show and Cameron was written out. The reason for this was unclear for quite some time. However, show creator and runner David Shore stated that the reason Cameron was written out was to show that not ever character to be around House was going to be corrupted.
Cameron came back one last time as a hallucination to House when he was in a burning building in the series finale. It is shown she has a child, presumably not House's child, but that of a man with whom she finally thinks she found happiness.
In eighth season finale we got to see the insight of House's mind where it was clearly seen that he saw all those people in hallucination whom he loved and those who left him for example Stacy, Dominika and of course Cameron. And in the end Cameron saved his life indirectly in the form of hallucination.
In the end, we can realise that she really loves House and vice virsa it is a beautiful love history and in the top their friendship it is beautiful and funny too
