Warp speed/FTL. Last season it seemed like it took La Sirena some time to get from place to place. Here, it seems like the Stargazer made it to the anomaly in a matter of minutes. Where is warp technology now after Voyager made it home? How far has the Federation expanded?
Since the ship was fitted with "Borg parts", maybe that includes modifications to the warp drive to include accessing the transwarp conduit?
