“Attention, Bajoran workers”: The Arsenal of Freedom (TNG) vs. Civil Defense (DS9)

It’s just one problem after another, as the Enterprise gets the hard sell from a long-dead weapons salesman, and the crew of Deep Space Nine sets off an old Cardassian security system.

“Starfleet is better with you in it”: Lower Decks (TNG) vs. Second Contact (Lower Decks)

We get a taste of life on the lower decks of the Federation’s flagship, and we’re introduced to the crew of the Cerritos, which is far from a flagship.

“Use logic more quietly”: Empok Nor (DS9) vs. Impulse (Enterprise)

Deep Space Nine and Enterprise get in the Halloween spirit, as Garak goes all Michael Myers on an abandoned station, and T’Pol finds a zombie apocalypse on board a Vulcan ship.

“I’ll try to make my lies more opaque”: The Defector (TNG) vs. Duet (DS9)

A Romulan defector and a mysterious Cardassian show us what true patriotism might look like, in two fine examples of Star Trek at its Star Trek-iest.

“You’re too late, we’re everywhere”: The Adversary (DS9) vs. State of Flux (VOY)

Suspicion and paranoia abound on the Defiant and the Voyager, as shape-shifting impostors and surgically altered spies force Sisko and Chakotay to question how much they can trust those under their command.
