Haven't heard that... but I did hear in one of the interviews that McGee will have a new l’amour interest this season... and a very passionate one at that!
I don't know if he is going to propose but I think there is some McAbby stuff happening this season :)
Shane Brennan has a dit there be a little bit of McAbby in a 'very unexpected way.' There's definitely gonna be some interesting relationship things that are gonna happen :)
