While just blurting out "He's a ghost" at the start of The Sixth Sense would have somewhat undermined the final twist, its not at all clear why one character in Fresh Bones is unable to make a fairly fundamental quirk of Chester Bonaparte's existence clear to Mulder and Scully.
Still, its nice to have X back even if his presence here is something of a surprise. We also find out the novelisation makes a lot of the episode's more nebulous plot details much clearer.
Colony is an amazing fast-paced episode. That also demands we refer back to Gender Bender in season 1 for our shape-shifting aliens and the implication. There is of course an implication that literally no one in The X-Files universe can be trusted now this concept has been introduced.
The final twist of Scully being a shape-shifting alien will be quite the doozy. Wait. Are we absolutely sure Scully is the one who came back in One Breath!?
(We are pretty certain. But you never know! Maybe this will factor into her decision to not be in any potential future seasons past 11)
