Brennan bent down over Parker, and tried to calm him down. She'd already called Rebecca, and knew that either she or Booth would be here soon. For now, all she could do was keep the other children away, so that the poor boy wouldn't be as panicked. The floor was clean and polished beneath them both, and Parker was lying down. Brennan was kneeling beside him.

"Parker, you know who I am, don't you?" She said. The little boy nodded, but said nothing, still struggling to get his breathing under control. Although she knew the boy didn't have asthma, Brennan had already sent Ange to get an asthma inhaler, incase it could be any help. She heard the hurried footsteps that she recognised as those of her friend and almost sighed in relief.

"Bren, Sweetie, here's the puffer," Angela said, as she crouched beside the two. "Your dad's got the other kids under control."

"Thanks Ange," Temperance said, and held the inhaler to Parker's mouth. She pushed the button on top and told him to breath in as deeply as possible. He did, and his breathing eased. They repeated the process a minute later returning Parker's breathing to his control.

By that time, Parker was curled up in Brennan's lap, and she was gently stroking the hair on his head. Tears were flowing down the young boy's cheeks, and Brennan wiped them away.

"It's okay, Parker," Angela whispered. "You've been very brave today, okay? Your Daddy or Mommy will be here soon. I promise."

It was as if her words were some sort of signal, because at that moment, the sound of Booth's footsteps rang through the the sound, Brennan tensed realising that this would be the first time that they two had seen each other since the disastrous meeting with Sweets. Still, Parker had been in trouble, and Brennan couldn't let anything happen to the little boy, no matter how things stood between her and Booth.

Booth didn't seem to care about the tension that had descended over her. He saw his son, looking a little scared and a little worse for wear, sitting in Brennan's lap, and was grateful that Parker was okay.

"Hey, Bub, come here!" he said when he got nearer. Parker smiled, and ran over to his father and jumped up into his arms. "What happened?" Booth asked the two women.

"From what I was able to ascertain, Parker went into a mild asthmatic seizure. It's not overly serious, but you should take him to see a doctor, in case it happens again," Brennan said, and handed Booth the inhaler, before moving back away from him. She was careful not to let her hand brush against Booth's.

"Thank you for helping him. Dr Brennan. See you later sometime, Ange," Booth said, and Angela nodded, knowing that that was Booth's way of saying we need to talk. Parker waved to both women, before his father carried him out of the museum, his footsteps echoing back down the hallway. Brennan fought back tears, and headed back to her lab, stopping to talk to her father briefly on her way.
