That there is no follow up where T’Pol’s rapist meets justice is a major crime. Perhaps the episode intended to portray that the rapist had friends in high places on Vulcan, and thus would be protected from facing any justice (which is an issue IRL), but was still no reason for Archer to limit his response to throwing the rapist off the ship and then have a quick talk with T’Pol.
At the same time, having the very next episode start with Archer taking pictures, and the episode being him chasing a shapeshifter to morphs not a woman in a nightgown probably was not the best way to follow up with it either. It should have at minimum, opened with Archer messaging Admiral Forrest about the incident. Especially since, even though it a bit narrowminded to focus on human crewmembers, it could have easily been any other member of his crew.
