Captain Spock:
[to Lt. Valeris]
Lieutenant, the torpedo hit, once again, please. [Valeris replays video] Captain Spock:
Hold. [replay pauses] Commander Pavel Andreievich Chekov:
It *is* Enterprise. *We* fired. Captain Montgomery 'Scotty' Scott:
That is *not* possible! All weapons *visually* accounted for, [to Spock] Captain Montgomery 'Scotty' Scott:
sir. Captain Spock:
An ancestor of mine maintained that if you eliminated the impossible, whatever remains, however improbable, must be the truth. Cmdr. Nyota Uhura:
What, exactly, does *that* mean? Captain Spock:
It means that we can not have fired those torpedoes, someone else did. Captain Montgomery 'Scotty' Scott:
Well, they dinna fire on themselves, and there were no the ships present. Captain Spock:
There was an enormous neutron energy surge. Captain Montgomery 'Scotty' Scott:
Not from us! Commander Pavel Andreievich Chekov:
A neutron surge that big could only be produced by another ship. Cmdr. Nyota Uhura:
Kronos One? Captain Spock:
Too far away. Very near *us*. Possibly *beneath* us. Captain Montgomery 'Scotty' Scott:
If there were a ship beneath us, the Klingons would have seen her. Captain Spock:
[pause]
Would they? Lieutenant Valeris:
A bird-of-prey. Captain Spock:
A bird-of-prey. Commander Pavel Andreievich Chekov:
*Cloaked?* Captain Montgomery 'Scotty' Scott:
A bird-of-prey cannot fire when she's cloaked. Captain Spock:
All things being equal, Mr. Scott, I would agree. However, things are not equal. This one *can*. Lieutenant Valeris:
We must inform Starfleet Command. Captain Montgomery 'Scotty' Scott:
Inform them of what? A new weapon that is invisible? Raving lunatics, that's what they'll call us. They'll say we're so desperate to exonerate the Captain, we'll say *anything*. Captain Spock:
And they would be correct. We have no evidence, only a theory which happens to fit the facts. Cmdr. Nyota Uhura:
Assuming you're right, Mr. Spock, why would they fire on their own president? Captain Spock:
