Just to note for the record that, in the brief live-streamed ordinations sermon, Fr. Pfeiffer acknowledged the defect of form in his consecration and claims to have received a subsequent conditional consecration by "Bishop" Webster.
It would be nice if there were video to support that contention, but it is likewise difficult to believe the ordinands would consent to being ordained without proof that he was conditionally consecrated, particularly as Fr. Pfeiffer acknowledged the defect.
Then again, the difference between probability and certitude is infinite.
