I had a question about the USS Defiant that has been used in a few episodes of Star Trek set inside the mirror universe. It has appeared in Enterprise, TOS, and was mentioned but not shown in Discovery. Here's the thing. Wouldn't Starfleet have records of this event and the ship from the time Archer crossed over into the mirror universe? At least this is what I had imagined, that maybe the crew on Discovery could have looked up the ships computer records and found this information.
