Quite an impressive resolution to the Taran'atar-L'Haan arc. I would guess that prime universe L'Haan already was a member of Section 31 based on not being able to find her initially and then a file magically appears, or having her MU counterparts katra drove her to join the Bureau. It does tie into my hypothesis that Sarina doesn't even know she's a Section 31 agent. Perhaps L'Haan is controlling her through mind melds as part of a greater plan to conscript Bashir into the group. And speaking of whom, is there anything to not following on that "private conversation" he had with Vaughn?
