I think Jadzia visiting the Hoobishan Baths (at the start of "The Way of the Warrior) compares very favorably with Mirror Ezri.

(Immediately after writing it, I had hit the Edit button to change it to "play the role of", but realized the original version fit this particular thread much better.)

She was also one of the two actresses to do the Borg Queen.

Maybe you could list the rules for when to take a shot of kanar while watching these episodes.

Now I'm wondering how a Trill with multiple personalities would be, after merging with a symbiont.

History says the riots on DS9 were due to the Circle.

A hostile alien is on the station, who can assume any form.

You should do a "UPN Teaser Writer" response to @avclub-0c3e626d1a287cdc48c77515c8dcc243:disqus 's Mad Space Nine.

That picture of Ezri and Quark…
For some reason, it has me thinking "reboot of Basket Case".

"The feeble wheeze before sticking a pinky toe into cold water" doesn't have quite the same umph.

The twins keep us on Alpha Centaurian time — a 37-hour day. Give it a few months — you'll get used to it.
Or you'll have a psychotic episode.

Bashir as Hodor… that might work.

This episode works, if the Mirror Universe is breaking the fourth wall.

I was disappointed that the writers missed a chance to reference the earlier episode. Ezri doesn't tell Sisko about Joran, maybe because Sisko knows first hand what Joran is capable of.

Garak: Please, do not do anything you see on this show at home.
Worf: It is NOT a good day to die.

Ezri: What’s taters, Precious? What’s taters, eh?
O’Brien: Po-tah-toes. Boil them, mash them, stick them in a stew. Lovely big golden chips with a nice piece of fried gagh.
Ezri: Spoil a nice gagh… Give it to us raw and wriggling! You keep nasty chips.
O’Brien: You’re hopeless.

“Did you say something, Ezri?”

Too much Buffy?
Where did you get such an outlandish notion?

Does the Encore Western Channel show "The Adventures of Brisco County Jr."?
