I like how Baal magically knew everything about the plan to capture Adria but had absolutely know idea that both the NID and the SGC knew where he was and that they sent a ship to get him.
Also wasn't it established that the Goauld was 'secretly' in charge of the The Trust -that the humans involved still believe fighting for Earth in their own way? so how an undercover human found out about probably the most daring and ambitious Goauld plot in recent times is a bit of a mystery.
More also: Adria Ascended in the Milkyway. . .so wouldn't she have ended up with The Others and even if -for whatever reason she didn't, Is there a reason The Others didn't destroy/imprison/'punish her as she was an ascended being in the Milkyway and had absolutely no intention of following 'the rules?
I'd love to see the empirical data that Tokra DR used to come up with the "host body is too weak" diagnosis and using it as a justification for not doing the implantation.
Because there is nothing in the Tokra's almost hopeless millennia long fight against the System Lords to make us think that they would do whatever it takes to accomplish their goals and that they would certainly risk the life of one to save the rest and the galaxy as a whole.
