Stana Katic & Nathan Fillion 

I miss this time. Stanathan on point

Stana Katic is SO GORGEOUS.

Hahahaha,, Stana at 2:09 is great!!,, I love them!!!

stana is sooo adorable (:

they are so adorable!! :)

Oh my, if you pause the video right at the beginning - that facial expression alone is priceless!!!

He loved you. Fillion might not have loved Katic but Castle loved Kate. Best show evah !!!

I can't hear what they are saying all I get is an annoying song. Does anyone know how I can get to hear this interview please? I really want to hear it :D

Things changed as Stana Katic's star rose as well as her popularity. Nathan Fillion clearly thought he should be front and center - jealousy and his fragile ego killed the show.

I can't understand a single word... There's just that music playing... :/

how come they don't do the interviews together anymore? What happend?

its abc's decision
