Footnote:
Hey, sorry if there was any confusion on the last chapter!
It was all real, House was just dreaming about what had happened! You know you can have dreams about actual events.
So no, nothing was fake, everything that happened did happen!
I hadn't ever revealed what Cuddy said to him while House was concious still on the table, so I thought it was a good time to do it. Basically he had never believed what he had heard until he dreamt about it again. Then looking over to see her sleeping in their bed together, he finally believed it and that's why he was smirking.
His dream was just a flashback of actual events!
Hope that clears anything up.
Thanks again to everyone who read this and gave AMAZING reviews!!
