i think he has been, but i guess he has his reasons. btw the "i dunno" picture of him is adorable!

Yeah, he's really tired and cranky that's why he's been acting like an ass i think. Doing Archer's surgery then messing up on that pregnant woman's surgery. And let's not forget about the ring too.

yeh i can understand why his ex wife is back and needs support and his ex friends aare all trying to remind him of him and his ex wifes good times, this being the very same time hes trying to find ways of proposing to the gf! hes got his reasons!

Poor thing, he's all frustrated with mixed emotions...I think his friends should stop talking about his past with Addison since he's already planning to propose and move on after all these year
Although I have to say the angry/cranky Derek is pretty scary... like o.O! *runs away*

yes he has been but he has the right to be mean like everybody else.
I was never really into the MerDer thing and not too crazy about Derek, but in the crossover I started liking him a lot more!

I think he is just tired and nervous about the proposal. He wants everything to be perfect.

i could understand why has been mean but in the promo for next week i dont like the way hes speaking to addies XD

YEAAH! And now he is going to get into a fight with Mark to :OO

agree with about everyone!!<3. It's good te be back here
