It's more like, he's not exactly angry at House for Amber dying, he logically knows that it wasn't his fault what happened. But at the same time if House hadn't been obstinate and such Amber would be alive, House would be fine etc. He's grieving as well and while he doesn't exactly blame House he's not ready yet to forgive him.

I really love the ducklings, especially the new ones. But then again I love a big ensemble cast. :3

Yeah sad epi and hurry up and watch Bones woman!
