AN: This is my first chapter in this collaboration. I hope you all like it! Especially percyjacksonfan135. Please know that this is my first time writing ABDL in the fan fiction world, so I'm just figuring it out, although I do read stories like this often. Enjoy!

Trauma of a Savior

Chapter 2:

Harry had never thought that roleplaying as a Little would be helpful to him, but it did. Not having someone who cared for him as a child was replaced by this secret. But he didn't have a Daddy to truly care for him. Not yet. But it was all Harry wanted.

He whined around a pacifier in the Room of Requirement, a safe space that could give him all he needed until he found his Daddy. He was dressed in khaki shorts and a white t-shirt that had a train on it. These were his play clothes, which he always dressed in when he needed or wanted to be little. Right now, he was debating chewing on the wooden blocks on the floor in front of him or just banging them together to make noise.

These thoughts ground to a halt when Harry heard someone say the password to get into the room. Turning to watch as the room let the intruder in without question, Harry startled and then crawled into the far corner of the room, starting to cry as he sucked anxiously on his pacifier.

Zacharias Smith stepped into the room, only to see Harry in the corner and stop.

"Potter?" Then he saw the pacifier and toys on the floor, "What's going on? Are you okay?"

Stressed and afraid, Harry could do the only thing he could while in his Little headspace. He burst into tears, loudly. Startled by the reaction, Zacharias shut the secret door and put a double-strength locking charm to keep all of the other Dumbledore's Army members locked out, even with the password, as well as a silencing charm.

"Hey, hey, there's no reason to cry. Just tell me what's wrong and I'll try to help you fix it, Pot- Harry," crouching where he stood to be more at the other boy's level, Zacharias smiled at the green-eyed boy, trying to seem safe and welcoming even though he had no idea what was going on.

Harry didn't care for the older boy's efforts at all. He just laid his head back on the wall behind him and cried, sloppy, simple words coming from his mouth.

"Da-dee, Da-dee… Wan' Da-dee…" and began to bang his head against the wall as he tried to rock to self-soothe, whether by accident or on purpose as some sort of self-inflicted punishment Zacharias didn't know.

"Whoa, whoa! Hey, Buddy, don't hurt yourself," Zacharias rushed forward to protect Harry's head, and so ended up crouched right in front of a sobbing Harry.

The boy's green eyes, wet with tears stared up into his own eyes for a long few seconds before something in Harry's expression seemed to change, and he suddenly reached up to the older boy as if begging to be held.

"What, what do you need? Can you tell me?" Harry, in his current headspace, could not, but his reaching arms became more insistent and he gave a soft, impatient grunt, "Okay, okay, I'll, um, I'll hold you…" Unsure, Zacharias took a minute to figure out how best to handle the shorter boy so as not to hurt him or cause him discomfort as he held him, and then picked him up as he stood, "There, you see? No need to be so upset. You want your dummy? Whoa, okay," Harry had hugged him tight and buried his head in Zacharias' neck, sighing, "Da-dee…" in contentment as Zacharias realized that he had just started a relationship with Harry Potter, and a rather unconventional one at that.
