Thor stumbled into the hall, straightening up and walking purposefully back to his chambers.
"You heard Loki," Thor murmured to Tanis, "No being seen!"
Tanis purred affirmatively, crawling under Thor's long hair and lying around the back of his neck, her tail wrapped around his throat like a choker necklace.
"Okay... good hiding spot," Thor muttered concededly, as one of the guards passed by without sparing them a second glance.
Thor got up to his chambers without any incidents, except for one of the castle staff asking him what was so funny. Thor had just shrugged and hurried off, not about to explain that there was a dragon hiding in his hair and tickling his ear.
When Loki was finally excused, he stepped out into the hall, walking back towards his chambers. There was a fair amount of activity, but as soon as Loki came into a dessert corridor he teleported himself to Thor's room.
As soon as he appeared, Thor whirled around, pointing one of his training swords at Loki.
"To what do I owe this hostility?" Loki asked, tilting his head to the side.
"Sorry!" Thor said, lowering the weapon. "You startled me."
"Oh? More startling than your chambers catching on fire?" Loki said, as the room started growing smoky.
"What?" Thor said confusedly, as he turned towards where Loki was looking, to see flames leaping out of the closet."TANIS!" Thor yelled. "Loki, can you put it out?"
"If you say so," Loki snapped his fingers once. Suddenly water swept out from the closet, quickly flooding the room.
"LOKI!" Thor shrieked, as the rush of water knocked them both over.
"I put it out, didn't I?" Loki gasped, popping up beside his brother, dark hair dripping.
"BY FLOODING MY ROOM!" Thor protested.
Tanis slithered through the water, climbing onto Loki's shoulder and digging her claws into his tunic. She trilled at him.
"Really?" Loki said, a mischievous smile curling across his lips. He swam over to the door and opened it.
The wave of water rushed out of the room, carrying Loki, Thor, and Tanis along with it.
And crashing straight into Odin.
"WHAT—" the Allfather started, before he found himself being swept down the stairs.
Several flights later, they were deposited down, soaking wet.
"Oops," Loki managed, giggling. "I wondered what that spell did."
"LOKIIIIIIIIIII!" Odin roared furiously.
"That was so fun! Let's do it again!" Thor said excitedly, jumping up and down and splashing happily.
"YOU WILL DO NO SUCH THING!" The Allfather bellowed, grabbing his two sons before they could take off.
"I'm sorry, father," Loki said, biting his lip and looking up at Odin piteously. "I didn't know that would happen. I was just trying to give Tanis a bath, but the situation got a little out of control..."
"You were trying to give the dragon a bath," Odin said, disbelievingly.
"Yes. Thor was helping me, and he accidentally splashed me, so then I splashed him, and then he dumped the tub of water on my head, so I tried to get him back by summoning water with magic, except the spell was much stronger than I'd previously thought." Loki explained, looking down and shuffling his feet nervously. "I can fix it though," Loki added. He waved his hand, and all the water evaporated.
Tanis withdrew her talons from the shoulder of Loki's coat and jumped down, spreading her wings to slow her descent to a feather's pace. She then trotted behind the Allfather and promptly set his shoes on fire.
"BY THE BEARD OF BOR!" Odin yelled in surprise, letting go of his sons to stamp the fire out.
Loki and Thor wasted no time in taking off running.
