SPOILERS ABOUT THE FINALE!!!! 

something happened to her the night before, and she is very happy about it.-----> Lucas proposed??? Then No broken relationship

Oh my gosh!!! I hope Lukas proposed to Cuddy & she'll merry him!!! Even if because of that House goes back on Vicodin, screw him! She is not responsible for him! What should she consider in first place is her & Rachel's happiness!

I was just fooling around, I came here because I was curious...and I saw this link....
It's so freaking hard not to read this...but I won't...

Cuddy is very happy!! This is what I want most of all. I wonder if is she pregnant or did Lucas propose or is it something else I haven't thought of yet??? Can't wait to find out.

Oh the haters on that community...anyway. I hope is Lucas related...I hope is baby...

I do not know if the source is reliable, but confirmed that the reason why Cuddy is happy is because Lucas has made the proposal!!!

I wonder what Cuddy's answer is... please not make us wait until season 7 to find out.
