I think he's looking for answers. What's going on? Why did Bishop Morgan recommend this priest? When he wrote the e-mail complaining about the priest, Bishop Morgan then blocked him? I think there's a question of trust here, where Bishop Morgan needs to be transparent about the entire thing.
From this link posted earlier https://www.pressreader.com/ireland/belfast-telegraph/20250415/281556591665695 it seems the predator was ordained deacon at the diocese of Fort-de-france (Martinique) and dismissed from the clerical state thereafter. From there, he moved to London, Cardiff, and now seems to be operating around Wales and Derry (Ireland). Thus he was never a priest in the first place. If he is presenting himself as a priest now, I would suspect this was because he was ordained by +Ballini, thus +Morgan could have relied on this information from +Ballini make the recommendation to Dr K? What a sad state of affairs that would be. I believe it would best for Dr K to reveal the details received from the diocese of Fort-de-france to clear this once and for all.
