Which episode of Voyager would you recommend to a DS9 fan?

[Leviathan]

Scorpion 1 & 2 matches the 'battling of empires' element and the overall tone.

...unless you didn't like the DS9 fan in which case recommend 'Threshold' or the 'Fight'.

Let's see . . .

If I didn't like the Deep Space Nine fan, I'd recommend "The Haunting of Deck Twelve."

If I didn't like a Kelvinverse fan, I'd recommend "11:59."

If I didn't like an original Star Trek fan, "Someone to Watch Over Me."
