It's not that hid things from Peter on purpose but even though Peter's past is pretty gnarly, Leo thought his was... if Peter knew it all would he think of him the same? Leo wasn't even sure he thought of himself as the same. He sure as hell remembered the looks on the faces of others who had realized everything, put together the pieces of his story. Leo never said much because he didn't want Peter to put together the puzzle and see how not worth Leo was, how messed up he actually was. He was sure Peter wouldn't want him and he didn't want to lose Peter.

So he didn't share anything too personal about his past. He'd always thought that'd been enough for Peter so far.

"I don't have a house," Leo answered, watching Peter's shoes kicking at the concrete and grass. "I live at a special camp for demigods. I spend most of my time sleeping in this workshop I have there...Mortals can't really go."
