"For the want of a marker

"Well, you see, that's another reason I can't help you catch this guy. I might adversely affect the fate of the future. I mean, his next victim might be the mother of the daughter whose son invents the time machine. Then the son goes back in time and changes world history and then Columbus never discovers America, man never lands on the moon, the U.S. never invades Grenada. Or something less significant resulting in the fact that my father never meets my mother and consequently, I'm never born. So when do we start?"

"You don't have to change much to change everything."
And the Bastard grant us, in our direst need, the smallest gifts:
the nail of the horseshoe,
the pin of the axle,
the feather at the pivot point,
the pebble at the mountain's peak,
the kiss in despair,
the one right word.
"Should a traveler appear earlier in the timeline of his own existence, he would be but as a pebble, cast upon still water... but the ripples he creates would over time radiate upon far distant shores, geometrically altering events in its path."
— Einstein, Farscape
"The Jean-Luc Picard you wanted to be, the one who did not fight the Nausicaans, had quite a different career from the one you remember. That Picard never had a brush with death, never came face to face with his own mortality, never realized how fragile life is, or how important each moment must be — so his life never came into focus. He drifted through much of his career, with no plan or agenda... going from one assignment to the next, never seizing the opportunities that presented themselves. He never led the away-team on Milika III to save the ambassador, or take charge of the Stargazer's bridge when its captain was killed. And no one ever offered him a command. He learned to play it safe. And he never, ever got noticed by anyone."

One wrong risk, one misplaced trust, one careless guess is enough to destroy the one thing you can least afford to lose.

Tim: Did you notice that everything that transpired in those three films - and I mean everything - can be attributed to the actions of one very minor character?
Brian: Who's that?
Tim: The gunner on the star destroyer at the beginning of the first film.
Brian: What do you mean?
Tim: Because, if the gunner had shot the pod that C-3P0 and R2 were in, they wouldn't have got to Tatooine, they wouldn't have met Luke, Luke wouldn't have met Ben, they wouldn't have met Han and Chewie, they wouldn't have rescued Princess Leia. None of it would have happened.

But, you only learn that when you start losin' stuff. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. The inches we need are everywhere around us. They're in every break of the game, every minute, every second. On this team we fight for that inch. On this team we tear ourselves and everyone else around us to pieces for that inch. We claw with our fingernails for that inch. Because we know when add up all those inches, that's gonna make the fucking difference between winning and losing! Between living and dying! I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. And I know, if I'm gonna have any life anymore it's because I'm still willing to fight and die for that inch, because that's what living is, the six inches in front of your face.

Break the sound barrier, there's a sonic boom. You broke the time barrier, time boom.
Sometimes a small thing can have large repercussions. If the driver of Franz Ferdinand hadn't been momentarily lost, World War I would have likely been delayed and taken a different form. If a cat hadn't been so crappy when it was trying to scratch up a bird with it's claws, the human watching it wouldn't have been inspired to create the cotton gin, which is considered by many to have been a contributing cause of the Civil War. It's been said that one of the Roman spies, observing a horse being bothered by some flies, was given the idea of how to get into the off-limits area of Carthage and would help ensure Roman victory over their mortal enemy. You're about to witness something greater than all of them from an act probably even smaller... and nobody knows it.
(Chiana spills a drink on a Peacekeeper commando, and apologetically wipes it off - taking the opportunity to steal the key to the commandos' secret cargo off him in the process)
And there it is. You have just witnessed the event that will change the galaxy.
Now that they've escaped, change is inevitable. Scorpius needs that wormhole technology to use against the Scarrans, and his interest in Crichton is going to compel the Scarrans to take their own interest, until the Moya crew are pulled into the midst of this massive power struggle throughout the series in the desire to secure the knowledge from Crichton. This wouldn't happen if Scorpius hadn't pursued him, and he wouldn't have done it if Crichton hadn't wound up in the Aurora Chair at this particular base, which he wouldn't have done except to save Aeryn from a mortal wound... a wound she wouldn't have acquired if Chiana hadn't decided to open that crate. As I said, from little things...
'Every great decision creates ripples, like a huge boulder dropped into a lake. The ripples emerge, rebound off the banks enough to see the waves. The heavier the decision, the larger the waves, the more uncertain the consequences.
Does the ship have issues? Yes, it does, and if you've gotten past Act 5 you know how it ends. It's...not pretty, and if you don't ship it, there are perfectly good reasons for that. However, in other worlds and universes, they could have been happy. It doesn't always need to come to a tragic, bloody end.

Annorax: Four billion years ago fragments from that comet impacted a planet. Hydrocarbons from those fragments gave rise to several species of plant life which in turn sustained more complex organisms. Ultimately several space-faring civilisations evolved and colonised the entire sector.
Chakotay: By erasing the comet I altered all evolution in this region.
Annorax: Past, present and future. They exist as one. They breathe together. You're not the only person to make this mistake. When I first constructed this weapon ship I turned it against our greatest enemy, the Rilnar. The result was miraculous. With the Rilnar gone from history, my people, in an instant, became powerful again. But there were problems. A rare disease broke out among our colonies. Within a year, fifty million were dead. I had failed to realise that the Rilnar had introduced a crucial antibody into the Krenim genome and my weapon had eliminated that antibody as well.
Chakotay: And you've been trying to undo that damage ever since, but each time you pull out a new thread, another one begins to unravel.

If [Jess Harnell] werent stuck on that island, he could have done great things like announcing "America's Funniest Videos", voicing thousands of commercials and promos and starring on countless cartoon series and animated feature films like Animaniacs, Transformers, Drawn Together and Finding Nemo. He even could have gotten to live in an awesome house that looks like a spaceship, drive a beautiful car and work with many famous and important people, none of whom would ever admit to having worked with him. But none of that happened because he got shipwrecked. Damn that f%&#ing island.
