Lt Benson,
I am the counterpart of your First Officer Mr Spock or, as some people have come to know me, 'mirror' Spock. I am writing to you with explicit permission from your Captain, who directed me to you, speaking highly of your knowledge in this particular area.
While investigating the reasons behind the divergence in our universes, I have pinpointed one potential point of divergence in the death or survival of a Terran woman in the 1930s. I have attached a list of music from my universe dated from around that era. If you have the time, I would appreciate it if you could correlate these records with the ones from your universe, and inform me of any differences you find.
My hypothesis is that the music released before that time will correlate one-to-one, while there will be minor or major differences in the rest.
Expecting your reply,
@realmirrorspock
Mr mirror Spock,
I must admit that I am not fully surprised at your writing to me, for I have been hearing stories of your messages being put through to our universe and the chaos they have been creating among the ensigns a few times already.
Since you asked me oh so nicely, I have already looked over the information attached, and found some discrepancies, just as you had theorized.
Please see the attached finalized report, and I say with confidence that it will contain the information you require.
Best regards, Lt Benson - USS Enterprise
