After a bad start with the usual Archer stupidness/naiveness that is essential to the plot (I'm starting to wonder if this isn't simply lazy writing... ), inviting a bunch of strangers (who as far as they know might be a serial killer convention) to just take an unsupervised stroll around their ship most sensitive areas (with one of them just calmly walking and sabotaging the warp engine (!!)), besides Trip giving sensitive technological information like if it were talking about the weather, we get to the meat of the episode.
Daniels (which if we have seen before I don't recall) is actually from the future, and he is here to stop Silik, who just saved the ship. Well, why couldn't he just stop him 1 day earlier and we wouldn't have a show anymore! I think the Temporal Cold War and how it is handled is actually quite cool, even if the future technology seems a bit too magical for me, but I guess that is the point.
What bothers me is that Archer, as usual, is so quick to pick a side. Come on, I know Silik isn't your best buddy, but he just SAVED YOUR FREAKING LIVES! And okay, Daniels is a human, but he is a spy that has been your ship for ages. Why are you so quick to assume this spy is friendly?
It is also bothering the usual "hey! Stop! Really, I mean it!". Am I missing something or didn't we see them use stun mode before? Why not just stun him and question him later? Anyway, I know this is an usual TV trope, but do you really have to do it literally 3 times in a row? When will you learn Archer, when?
