History Recap / TheOrvilleS2E4NothingLeftOnEarthExceptingFishes

* TheReveal: Janelle is Teleya, having been surgically altered to look human, and placed on the ''Orville'' as a spy. Great, that's ''all'' Ed needed.

* SeeTheInvisible: The Krill marauders release drive plasma to expose Ed's shuttle despite its InvisibilityCloak.

* ScrewTheRulesImDoingWhatsRight: Ed breaks protocol to return Teleya to her people in spite of her crimes, hoping it will help open dialog between the two species. Teleya doubts it will change anything.

* PrimalFear: According to Ed, it's normal for some races to get rabidly xenophobic upon discovering that they're not alone in the universe. He assumes that the same thing happened to the Krill, since his study of their history indicates that they weren't even close to being the {{Church Militant}}s they are now during their pre-space days.

* YankTheDogsChain: Poor Ed. He finds the perfect woman to move on from only to discover she's a Krill who hates his guts.

* AlwaysABiggerFish: Ed's shuttle is captured by a Krill destroyer, which is later stomped by a much larger Shak'tal warship.

* DoubleTap: The Shak'tal boarding party methodically does this to all the Krill they have gunned down.

* EnemyMine: Teleya and Ed have to work together to escape the planet and the pursuing Shak'tal, a proposition considerably more difficult for Teleya than Ed.
* EvilVersusEvil: The Krill ship is attacked and destroyed by the Shak'tal, a brutish race that the Krill are at war with. While Teleya explains that the Krill started the hostilities by wiping out one of their colonies, the Shak'tal appear just as eager to engage in a bit of GuiltFreeExterminationWar.

* EnemyMine: Teleya and Ed have to work together to escape the planet, a proposition considerably more difficult for Teleya than Ed.

!!Tropes:

** When Gordon applies for the command track, which Kelly accepts, Bortus waits for him to leave the room then tells her "He will fail."

* TheBusCameBack: Teleya returns after her last appearance in season 1's "Krill".

* CantKillYouStillNeedYou: Ed asks why Teleya doesn't just kill him right off when they crash on the moon. She says she needs him to carry the communication gear and, as much as she hates to admit it, can't handle the raiders on her own. This comes up again later when they realize a day on this planet can be nearly a month long and Teleya needs Ed to get into the sunlight to set up the signal. Ed openly tells her "you can shoot me or you can trust me" as he walks out with the beacon.

* CrazyPrepared: Ed appears to give up some command codes to save Janelle from being tortured. After the truth comes out, Teleya asks about the codes. Ed admits it's actually a special database used just in case of these emergencies and it would have taken the Krill weeks to realize all the information inside it was false.
* EndlessDaytime: The planet Ed and Teleya land on has days that last nearly an entire month, which is problematic considering their rations will only last a few days. Ed convinces Teleya to let him activate the emergency beacon alone.

** Janelle Tyler being a Krill agent physically (and painfully) turned into a human is reminiscent of [[spoiler:Ash Tyler]] being a Klingon sleeper agent on ''Series/StarTrekDiscovery''. (They even [[spoiler:have the same last names]].)

-->'''Teleya''': [Janelle] no longer exists. She ''never'' existed. ''(in Janelle's voice)'' We should take a trip. When was the last time you actually had time off?

* NiceJobBreakingItHero: Teleya had been a nice teacher until Ed's killing of the Krill crew (and her brother) turned her into a true fanatic.
