Somehow, it got out. I don't know how, and there's nothing to be done for it anyway.

[Colin shakes his head, carrying AZ to the quarantined ward.]

We're looking at a very bad scenario for the Bastion. I think the Pokemon might have been carrying the virus out... I don't know for certain, and I don't have a suitable medical scanner. But we've had little ones running about. I should have shut that down... But the Quarantine has been too lax. Again, nothing to be done about it now.

[He sounds more irritated than usual.]
