I personally don’t mind the little spider assassins, I think they dial up the horror aspect, though I’ll admit in terms of pacing cutting the probe antics does more good than harm. But yeah I can do away with Obi-Wan’s “staged accident” at the beskar mine.
This should remain episode two, since the Christophsis stuff does all the necessary to establish most of the vital characters (Ahsoka, Captain Rex, Ventress) that anchor the show. Besides, seeing how the Mandalore episodes are better written and more in-depth, the Christophsis events would feel rushed if they come second.
I like “The Death Watch” for the title.
