Ok I know why there was no men aloud in the convent But, How come in season 2 Father Lundy and Marcco the great's big butt:) get to stay in the convent's spare room.The only one that had to stay in the Gardner's hut was Carlos.LOL

Because if Carlos came within so many inches of Sister Bertrille, they had to have a story conference with the Church media liaison. lol Gosh, I wonder why.
Their UST was apparently obvious to even Church media folk.

Exactly.....Since Carlos was worldly and not a priest, it wouldn't look proper for him to stay in the spare room.
