See, this I can believe and understand. But I do find it difficult to think that any episode with Diaz as a semi-major part of it (as it seems he is) could be one of the best/favorites of the entire series. But I am well aware that's my hatred of Diaz affecting my judgment and I'm perfectly okay with that.
I do wonder if it'll feel like a bit of a reboot of Diaz, in the sense that the Diaz we'll see tonight is one that ignores every single previous episode he's been in and suddenly he'll actually be a "big bad" level threat. If so and if that's what they want me to think, I'm going to need them to erase my memory of S6/701-706 Diaz using one of LoT's devices.
