In episode 3, Hugh says that as far as he knows, the XBs on the cube were the only Romulans ever assimilated...if so, what about the Romulans that were at the outposts that were scooped up in the TNG episode "The Neutral Zone?" Could these in fact be the same Romulans and the cube had been drifting since the early TNG days? How long was it cut off from the collective before the Romulans reclaimed it? I do think it is interesting that the assimilation of the Romulans caused problems within the collective, like they had some anti-Borg program in them. This supports the theory that they are something like BSG humanoid Cylons. Also I hate to bring Beta canon into this but it seems somewhat similar to the Caeliar/Borg situation from "Destiny."
