During Shard's coma, the priest took the keys from his pocket, went to No. 6, Saint Delan Square, and placed the items that were inconvenient to bring into the church into his home. He also brought back a change of clothes and used the coat with one sleeve, which was imbued with Shard's scent, to bring Mia, who had temporarily no one to feed her, to the church.
"When I opened the door to your second-floor room this morning, your cat almost dashed up to scratch my face. The little fella probably thought I was a thief."
The priest said this but was not angry at the orange cat; he probably liked cats a lot:
"However, it is indeed well-behaved when it's around you. If you don't have time in the future, you can send it to stay at the Dawn Chapel. Not just for catching mice, the young nuns here are all very fond of cats."
