When that old Lady said, she didn't want to let that damage thing bring back to the house,...

I think that more than an illegitimate child, she thinks he's damage because of his illness and the fact that he can't feel heat or warmth, which is just as screwed up.

I'm not sure but i thinks maybe it's because of Giovanni's illness, like he is "dammages" 'cause he can't feel the heat

Oh okay. So that's the reason why they sent him to an orphanage right???

I'm guessing, I'm not a hundred percent sure, but that would make a lot of sense.
