Episode title swap challenge

[at Quark's]

Just a little game I thought up: Find 2 episodes that would bear a title swap well.

For example:
Q Who (meeting a lot of Q's embroiled in a civil war)- The Q and the Grey (Q introduces the Borg to the Federation).
Displaced (Voyager is transported to the Delta Quadrant)- Caretaker (Nyrians take care of Voyager and her crew now).
Random Thoughts (a collection of random Riker memories)- Shades of grey (Tuvok shows that reality may have more nuance than the Mari justice approach allows for)

Can you find more ?

 

[Orac]

Whom Gods Destroy
Captain Picard investigates the survivors of a destroyed colony.

The Survivors
Captain Kirk visits an asylum for the few remaining incorrigible criminally insane of the galaxy.

 

[Tosk]

The Emissary (TNG) and Emissary (DS9)

 

[Xhiandra]

The Emissary (TNG) and Emissary (DS9)

Oddly enough, I don't think that one works. The TNG episode's title refers to a specific emissary, not the function. It's about K'ehleyr.

Cheating a bit:
The Naked Time (TOS) and The Naked Now (TNG).

 

[Willsky7]

Whom Gods Destroy: the crew of the enterprise discover a race of aliens claiming to be the Ancient Greek gods.

Who Mourns for Adonis: Kirk and Spock are held captive by a famous starship captain, inside an asylum for the insane.

 

[at Quark's]

Move along home: Vash wants to move along home. Vash wants Q to move along (home).
Q-less:Just what it says on the tin: no trace of Q in this episode.

[JirinPanthosa]

Wrongs Darker Than Death Or Night <===> Shades Of Grey

(Because the latter is a wrong darker than death or not, and the former discusses moral shades of grey.)
