Well, it was also the Arcana who did the separating, according to Maria-chan. Not exactly normal circumstances, or anything we can really use as a test. I don't know if that was close enough to the end of the walkabout that they would've bothered with the usual procedure or skipped straight to 'well, everyone will be here soon enough anyway.'

It wouldn't... but I'm not sure if it would just be a network goal. I mean, you'd need to not only be able to pull their mind out but give it somewhere to go.
