The destruction to which I refer would leave no parts remaining. However, I disagree. If they had... "half a brain" [He uses her phasing, more to be quaint than anything] there would - will - be a failsafe to render at parts left within the enclosure inert if not remove them entirely without the need to resort to retrieval.

[A pause. Admittedly, as he talks to himself her own solution doesn't seem unappealing. Just rash, impatient. Impractical? Yes, that too. Something John Crichton would have come up with.]
