10 Star Trek Timelines That Were Erased

How must it feel to carry the weight of death on your shoulders? Harry Kim felt this, not just for one person, but for the lives of his entire crew, in the episode Timeless. He blamed himself for Voyager's crashlanding, from which only he and Chakotay escaped, zooming ahead in the Delta Flier.

That guilt weighs a person down. As the years went on, neither man could stomach it, so they set about changing the past. They stole a temporal transceiver from Starfleet, 'reclaimed' the Flier, and found the remains of their old ship and crew. The plan was simple: send the corrected data back in time, and save the crew. Easy, right?

Not quite. The USS Challenger appeared, captained by none other than Geordi LaForge. He posed a question to which they did not have a simple answer: did they have the right to change history so? Fifteen years had passed since their return home, full of joy, sorrow, and everything in between. Who were they to decide that didn't matter? 

Frankly, by the episode's end, that question remains unresolved, even though Harry does change the past. Timeless then is similar to Children Of Time. Though as an audience we are happy to see our familiar crews survive, did Odo or Harry truly have the right to erase what they did?
