Disclaimer: I only own Sean. Nobody else.
Author's Note: You guys have to understand something about the way Sean overreacts in this. In this story, he's only lived with the Third Doctor and UNIT for a little over a month and while his appearance and mental, as well as somewhat emotional, state declare otherwise, he is actually only about six months old. (The reason why is a lot harder to explain.) He is overly sensitive and is scared whenever he does something wrong, fearing the Doctor or one of the officers will hurt him.

"Brigadier, have you seen Sean?" Brigadier turned around when he heard the Doctor's voice.
"No," he said, frowning when he saw the worry on the Gallifreyan's face. "I'm sorry. What happened?"
"I don't know exactly," the Doctor said. "I was doing something and I guess I didn't realize he was behind me and I accidentally threw my arm back too fast and hurt him. He ran out of the lab before I could explain anything and that was an hour ago!"
"Let's go looking for him then."
As the Doctor had already looked through most of the UNIT HQ, he and the Brig decided to search the rest of the place. When this went to no avail, they searched the enitre HQ a few more times, each time with more soldiers accompanying them to make sure they had not overlooked anything. It was on the last effort, just before the Doctor decided to give up and go looking for him in Bessie, that one soldier pointed out muffled noises in a nearby closet. The Doctor hurriedly flung the door opened only to find Sean curled into a ball, whimpering and holding a blood-covered rag to his face.
"Sean," was all he muttered as he knelt down and attempted to touch him. "Sean, I-"
"Don't touch me!" Sean scremaed, his reflexes kicking in, making him jump back in what little space was possible. His face hurt too much to continue screaming. "Don't...!"
"Is it him?" asked the soldier who pointed out the closet.
"Yes, thank you for telling us about this," the Doctor said as the Brig appeared in the doorway. "Sean, I'm sorry. I didn't mean to hurt you."
"That's what they said," Sean muttered, tears welling in his eyes. "That's what they always said, the people I was with before I ran away. Whenever I got hurt they would say, 'I'm sorry, I don't want to hurt you, I don't mean to'." His tears fell. "I saw the glee on their face. They were lying to me...!"
"Sean, you know I would never intentionally hurt you." Gently and slowly, the Doctor placed his hand on the one holding the rag. Carefully, so as not to further injure, upset, or anger the boy, he dabbed at the blood, not even caring that little spots had found their way on to his silk shirt. "I didn't know you were so close behind me. It's my fault for not checking." The Doctor pulled the rag away. Sean's nose was bleeding, of course, and was swollen, beginning to turn purple. "It does not look broken. But then again, I'm not a medical expert." He began dabbing again. "I really am sorry, Sean. It's all my fault."
"No, it's not." The Doctor stopped what he was doing and raised an eyebrow. "They always did it to me when I did something wrong. I guess when you elbowed me, my instinct took over."
"It's OK, Sean, I realize that." The Gallifreyan helped his son up. "Come one. Let's take you to sick bay to get you checked out."
Just as the Doctor had suspected, Sean's nose was not broken. Though it took Sean a while to stop shaking, he felt much better after the Time Lord had promised to take him somewhere special the next day: ice cream! Even if Sean didn't know what it was, he was excited!
