Having both a Starfleet spy and a cardassian spy in the cell was obviously more of a coincident, as I see it.
Maybe Chakotay's cell was successful in their missions and therefore attracted the interest from both Cardassians and Starfleet?
But I can agree that Chakotay maybe was a bit naive in his hring of people. He saw the good in them while someone like Eddington would have been more suspicious.
That turned out to be devastating. He didn'tonly have Tuvok and Seska. He also had problems with Jonas and Suder, if not in the Maquis cell so later on with Voyager.
He did have some problems with Paris too back then.
Chakotay: the ideal Maquis (hell, he's as close as you can get to a poster boy for the movement).
Eddington: the "realistic"/cynical take on the Maquis.
For some strange reason I like both of them!
But one thing I often wonder is:
Was there a real Seska?
In the Deep Space Nine episode
Second Skin, Kira is kidnapped by Cardassians, her face is altered to a cardassian face and they ty to persuade him that she actually is an Obsidian Order member named Iliana Ghemor who has been altered to take over the identity of Kira in an attempt to infimltrate a Maquis cell. The real Kira is supposed to be dead.
We also had O'Briens old friend Boone who shows up on the station Deep Space Nine in the episode
Tribunal. But the real Boone is dead and the person who visits the station is an Obsidian Order agent whose mission is to frame O'Brien.
Of course, this is a plot by the Obsidian Order to discredit Iliana's father Tekeny Ghemor. Kira is no Obsidian Order agent and the real Iliana has disappeared during another mission and is supposed to be dead.
But what if there was a real Seska and the one we saw in Voyager was someone who had taken her identity?
In that case, what happened to the real Seska?
Wouldn't that be something for a future Voyager book?
