Bruce picked up the small Wally as carefully as possible and ran as fast as he could (his cowl back on) to the infirmary without jostling Wally too much.
When he reached the infirmary he carefully laid Wally down on a bed and got a doctor in there as fast as possible.
Bruce had called the founding members into the conference room to tell them about what had happened.
"What is this about, Batman? And where is Flash?" asked Superman as soon as everyone arrived.
"Well, the two questions are connected," Batman said in his usual monotone.
"What. Happened. To. Flash," Shayera ground out.
Batman sighed and started to explain, "Somehow the Flash has reverted back into his 5-year-old self." At that all the women founders awed and tried to get up to find him. "Before you see him you have to understand something. Wally will probably kill me if I tell you this, but you need to know."
Green Lantern looked at Batman and said, "We all know that you and Wally have been dating for a while now, but what makes you so sure that you know him better than any of us?"
Batman sent a Bat-glare at GL's direction and before he could speak Dr. Johnson came on over the comm. in the conference room saying, "Batman, we have him stabilized. He keeps saying that he needs you and I can't get him to calm down."
Batman responded with, "I'll be there in a minute Dr. Johnson. I have to finish explaining."
At that everyone just stared at Batman dumbfounded. Batman just sighed and started explaining again, "I know him better because he's told me about his past."
"What about his past?" asked Wonder Women.
Batman looked up and started again, "He may seem happy, but that's because he doesn't like to stay in the past. Out of all of us, including me, he's had the worst childhood."
At that point, Superman interrupted, "How is that even possible?"
"His father, Rudolph…"
Yet again Batman was interrupted by Superman, "I thought Wally's father was Barry Allen, the previous Flash?"
Batman sighed even deeper this time and continued, "That was the case after he was adopted. No more interruptions.
"Now, as I was saying, his father, Rudolph, and his mother were very happy, then, on Wally's birthday, his mother died. His father blamed Wally, which in turn made Wally blame himself. Soon after his 5th birthday Wally's dad began beating his own son and he would always put Wally down. Through the yeas the beatings got worse. It was even worse after his dad found out that he became Kid Flash and could heal faster."
After he had laid everything he dared to on the table, Batman let this information sink in. After a while Dr. Johnson came back on over the comm. "Batman, he has fallen unconscious, but he keeps muttering in his sleep for you."
"I'll be there in a minute," Batman said. He then turned to the other founders and asked, "Any questions or can I go to his side now?"
Everyone looked at each other until Superman finally spoke up, "You can go on, Batman."
With that Batman left them and went to his Wally to try and comfort him.
