Molly O'Sullivan is back! So far, this story had zero connection to the first story off the boxset,  but I'm sure everything will tie together somehow. We also got the Eighth Doctor meeting the Viyrans, though there's no mention of Charlie (or Mila). The bits about the development of modern biological warfare is good, and Eight/Molly is just a great duo. Still, the actual plot was a little boring/confusing, but hey, we move.
