Huey, Dewey, Louie, Webby, and Scrooge all approached the light temple with caution. This was the fourth of the many elemental temples across the globe that the five of them had visited, and each one contained a beautiful magical rock, endowed with different powers. They'd braved the fire temple, the earth temple, the water, and lightning temples already, and had come very close to making off with each of the rocks. However, so far, each time they had failed. Scrooge didn't seem like he was going to give up anytime soon, though. There were three more temples to try, after all.

"Now remember lads, and lass," Scrooge said, "this temple is the most important one of all. The stone it contains gives off-"

"Light!" Webby cheered.

"Well, yes, but it also contains a rather stupendous all-purpose healing serum. It can cure any disease-"

"You've found the cure for cancer?" Huey exclaimed.

"Any bacterial-based disease."

"Aw."

"So, what are we waiting for? Are we Dewey-ing this? Or are we gonna dew-ny ourselves this dew-lightful oppor-DEW-nity, being daring-dew adventurers, like we dew…Dewey…" the blue triplet trailed off.

"And here I thought it couldn't get any worse." Scrooge said. "Kids, this is very important. Your mother and uncle, and your…." He looked at Webby. "-Cousins, I think, are back at home sick with a bacterial infection from the dragon kingdom we found last week. As you may have noticed, the symptoms are somewhat serious compared to previously discovered maladies…"

"Uh, yeah, it's pretty serious." Huey agreed. "Uncle Donald sneezed fire right through the side of the house."

"Which is why we're here to find this rock!" Scrooge boldly concluded. "Zeus above, I hope it's a bacterial infection…."

The five of them walked through the doors of the temple to reveal a splendorous light show. There were thousands of floating multicolored lights all burning like mini suns and swirling around each other, illuminating the whole room. "Whoah…. It's beautiful…" Webby said, staring up in awe. "Eh, don't bother." Scrooge said. "It's probably some magical trick to keep us from reaching our goa- CURSE ME KILTS!" Scrooge had nearly stepped into a massive pit of white snakes. They all glimmered as if they had diamonds for scales(which they probably did), and a look of death glinted in their ruby red eyes. They all hissed menacingly at Scrooge as he backed away from the pit.

"It goes across the entire chamber!" Huey pointed out. "How do we get across all these snakes?"

Webby stepped forward with a grappling hook. "Easy. Hi-yah!" She shot the rope across the cavern and it hooked onto a rocky pillar at the other side. "Just head right on over. Simple!"

"No falling, kids." Scrooge called, already tightroping across after Webby. Dewey jumped on after them, holding his arms out for balance. Huey was about to jump on too, until he noticed Louie standing there. He was staring at the ground and squinting, as if he was having a hard time seeing. "Uh…. Hey Louie, you coming?" Huey asked. Louie didn't respond. Huey walked over to him. "Louie, are you okay?"

"No….." Louie said quietly. He sat down on the floor and covered his eyes.

"You coming, lad?" Scrooge called, now on the other end of the pit. "No,

I'm gonna stay with Louie!" Huey responded. He knelt down on one knee in front of him. "Louie, how many fingers am I holding up?"

"I don't know…. seven?"

Louie had uncovered his eyes and was squinting hard at Huey's two fingers he was holding up.

"No, not seven."

"Eleven?"

"No." Huey said, genuinely starting to panic. "Um, UNCLE SCROOGE!"

Scrooge didn't respond. He was halfway through a spiky obstacle course with Dewey and Webby.

"Louie's broken!" His voice echoed in the cavern.

"Louie's always a little broken!" Dewey called to his brother, echoing back.

"No, guys, he's like, extra broken!"

Silence. Then,

"Keep an eye on him! He'll be okay. Just help him across the bridge." Scrooge directed.

Huey cautiously guided Louie over to the tightrope and across it. It was extremely difficult keeping himself and an extra person balanced. There were several times where Louie almost directly stepped off of it and one time when they were literally hanging above the pit of snakes, but somehow they made it across.

"Whew… glad that's over…" Huey said before looking up too see the aforementioned spiky obstacle course. "Aw, phooey…" he said to himself.

After the five of them had finished the several trials, Louie having nearly killed them in the process, they finally reached the pedestal displaying the light stone. Scrooge stared at it for a long while. "Out of all the treasures I've ever beheld, this is the most mesmerizing."

Louie crumpled to the ground, burying his head in his hoodie. "Pain…" he said.

Huey quickly ran over to his brother in a panic. "Louie! Louie! Are you alright!?" Louie responded by whimpering and rolling over. The three other children all ran over to Louie and surrounded him(Scrooge was still occupied with the stone). "You guys, something's wrong with Louie!" Huey quickly explained. "Well, we can see that!" Dewey said.

Scrooge finally turned around. "Bless me bagpipes! Lad, what on earth is the matter?"

"I dunno…..pain." His eyes were unfocused and watering a lot.

"Oh! Actually, I think I know what this is!" Huey realized.

He began reciting a memorized Junior Woodchuck rule:

"Junior Woodchuck rule number seventy three: delirious and sensitive to light means traumatic brain injury!"

"Um… what does that mean?" Dewey asked. "And how is that a rule?"

Ignoring his second comment, Huey continued: "A traumatic brain injury is damage to your brain by made by some external force, such as a fracture of skull, or something hitting you hard in the head…" Huey suddenly remembered what had happened a few days ago. When in the airplane home after rescuing Fenton and Louie from a kidnapping, Fenton had mentioned something about being hit over the head with a frying pan…..

Huey stopped reminiscing and immediately got to work. "Scrooge, grab the stone and let's get going. We need to get Louie to a doctor." Scrooge nodded and ran over to the pedestal. Huey tried to pick up Louie to carry him and immediately failed. "It's okay, Huey, I can help carry him." Webby offered. She then easily hauled Louie over her shoulder and started running towards the exit.

"Wha- how- you know what, I'm not even gonna ask." Huey said.

Ring. Ring. Ring.

"Hello?"

"Hi, Fenton. It's Huey."

"Oh, hey! What's up?"

"Uh….you remember a few days ago with the…"

"The hostage situation?"

"…Yeah, that."

"What's wrong? Have Mallory and Doyle already escaped prison? Do you need me to come to-"

"No, nothing like that. I was just wondering, do you remember what happened when you and Louie were captured?"

"We…well, we were captured…Huey, what's going on?"

"It's Louie. He's been acting strange ever since that day! He's sensitive to light, he's even more unmotivated than usual,"

"Junior Woodchuck rule seventy three, delirious and sensitive to light-"

"Yeah, it means traumatic brain injury. I know." Huey said. "But this seems like more. What exactly happened at the villains' lair? Also, you were a Woodchuck? You memorized the guidebook too? You've still got it memorized?"

"Yes, yes I was."

"Really? That's amazing! You should come over and help me and Boyd earn badges sometime-"

"Huey, we were talking about your brother's traumatic brain injury?"

"Oh yeah! Anyway, FENTON HELP I DON'T KNOW WHAT TO DO-"

"Huey, calm down! Just get him to a doctor and it will be fine."

"Right. Thanks, Fenton."

Huey hung up the phone and looked over to Louie, who was laying down across two seats of the plane next to Dewey and Webby. He walked over to them and Webby looked up at him. "What did he say?"

"He said we need to bring him to a doctor."

"Um…. we don't have a doctor." Dewey said.

"What!? Why not!?"

"Because I'm not going to waste my money on some hack with a degree." Scrooge said, walking up to them. "Instead, I'm going to take him to the most skilled person I know…"
