It took Michael a while to squeeze the answer out of his mother, but he got everything he wanted.
His mother reassured him that Danny's soul was probably a Living Soul with an affliction of a weakened Curse. That was the most likely outcome given the current circumstances.
However, the weakened Curse was bound to grow stronger in the presence of Michael. He was still a Lesser Lifeform but he had already unsealed three Cursed Seals. That shouldn't have happened, and it made it increasingly more difficult to predict the time his next Cursed Seal would be unsealed.
The weakened curse affliction would increase around Cursed Children and Cursed Users with more unsealed Cursed Seals as well, but Daniel and Michael had been really close. Danny's Curse was the most compatible with Michael, therefore accelerating the recuperation process of Danny's weakened curse.
