My favorites are Memento Mori, Milligro, and Small Potatoes, I love the first two because of the emotion in them and I love Small Pototoes because it's just so funny.

I don't know, there's so many I love, but Jose Chung's & PMPP for the humour, redux 2 for the Mulder angst, tooms & squeeze, irresistable, home cos their creepy, theirs too many to choose from...

Unique:all things

Yeah Tunguska/terma is one of my favourite mytharc eps I love Krycek

I don't know, there are so many good ones. I really like Extinction 1 and 2, though. And bad blood, because it's so funny.

I love D.P.O. I'm not too sure why though:P And I also LOVE season 8 and 9 because it has Doggett and Reyes in it.
