I’m hoping that ends up making more sense because currently it’s just confusing. There needs to be an explanation as to why the cube crossed timelines just by trying to travel back in time.
I always think about Data's head in "Time's Arrow." When Kirk and crew are walking around San Francisco looking for Humpback Whales, Data's head is there, under the ground. When Sisko and crew travel back in time to the Bell Riots, Data's head is there, under the ground. When Zefram Cochrane takes his first warp flight, Data's head is there, under San Francisco's streets.
And when the
Kelvin is prematurely destroyed, Data's head is buried under the San Francisco streets. When the
Enterprise-D assists the
Enterprise-C near Narendra III, Data's head is under San Francisco. In these cases, it's an artifact of a timeline that never was and never would be, made by someone who may or may not exist, filled with memories from another timeline entirely.
Thinking in this way leads in directions more
Doctor Who (the overused "timey wimey," anyone?) than
Star Trek, but the DTI surely has a repository of artifacts from the never wases and the never will bes.
My point is, time is weird. And weird, as Janeway once said, is what Starfleet does.
