Helping Harry (слэш)

Marcone comes across Harry having a breakdown in the middle of the street (like the one he had in the Blue Beetle) and ends up taking him home with him because no, he is not leaving Harry alone like that. Afterwards, he and Harry work out a contract that Harry will come to him whenever he's feeling that way to avoid the risk of something happening to him when he's vulnerable. Harry comes back sooner than he would've expected.
