What the hell qualified him??
Taking a risk of being dismissed from Starfleet and ending up in prison just to restart the NX program? It’s alluded to as much in “First Flight”. Restarting the NX program is different from disobeying orders from mission control and causing the NX program to be put on hold indefinitely. It certainly does not reflect badly on Archer.
Looking at the ENT bible, there were some definite missed opportunities to flesh out the various relationship dynamics in ENT (namely Trip-Mayweather, Reed-Mayweather, Archer-T'Pol-Mayweather, and T’Pol-Hoshi) and histories, while simultaneously maintaining the focus on the trinity of Archer-T’Pol-Trip at the same time. The series should have referred its bible to get some ideas to further flesh out characters and their histories and various subplots. While other series benefitted from not following their bible, Enterprise was not one of them.Having recently read the early series bible, I'm dismayed how little there is in there too about anyone or anything. It's like they didn't think anyone would notice or care and would just be like, MOAR STAR TREK EPISODEZ.
Sigh.
That Trip was originally supposed to be ranked lieutenant, and there was a perfect opportunity in “Cogenitor” to follow through on this idea, only for Archer’s response basically boiling down to “I’m angry and disappointed. Dismissed.” No serious punishment beyond that. I wonder if witnessing A.G. not being demoted for causing the NX program to be put on hold indefinitely influenced Archer to not demote Trip for something that would probably be considered worthy of demotion with any other captain? Or if the protocol at the time was simply to boot troublesome individuals out of Starfleet and there was nothing Archer could do at the time since he was millions of miles away from Earth and still needed Trip. And then the Xindi attacked Earth, and he needed everyone wiling to participate. But that he did not even bother to consider promoting Reed to be his second officer at that moment is kind of worrisome. Archer's era is definitely more lax than Kirk's era.
