The overall Rutherford arc was less successful. I guess they seeded it previously, but I always just assumed his implant was on the fritz, so it was odd to see him suddenly blaming the ship.
I am at a loss as to how Rutherford’s implant could be flexible enough to function as part of his brain in day-to-day life, and yet somehow be incapable of helping him solve engineering problems on an old ship? Is there some kind of weird DRM installed that prevents it from opening schematics older than a couple years? Or is all the data on California class systems stored in a file format that they latest and greatest starfleet tech can’t open? Both of which would be rather colossal failures of Federation computer tech.
The showrunners said from a very early point that the two would not get together during the shows run, and I get the distinct impression that they actively enjoy trolling shippers. So this is pretty much exactly what I expected, and I’m perfectly happy with it.
(Also, look at Tendi in that last scene, when she gets a scan of Rutherford during a conversation about them being “just friends”. She saw something on that Tricorder which she didn’t expect, and then when Rutherford gets up and has his back turned, she’s clearly checking him out. Draw your own conclusions.)
