He walked to their bedroom to find another note on the back of the one that he'd left earlier that day:

Clark,

Had to go to Themyscyla. Will be back soon-ish. xoxo

-Dianna

Clark was confused. Maybe Donna knew something he didn't.

When he arrived at Titan's Tower, and knocked on the door, Beast Boy answered.

"Hi, there Gar, is Donna in?"

"I don't know who you are, where you came from, or how you know my name, but she isn't here. Now go away."

Clark took off his Glasses and opened his shirt.

"Oh. Sorry Mr. Superman, sir, uh, come right in."

they walked toward the top floor, and turned toward Donna's room. But all they saw was a note on the door.

Titans,

went home. Don't come looking. Be back eventually.

Love-

Donna.

At that moment the door knob began to turn. And then it stopped. Clark whipped around toward Garfield Logan.

"I thought you said she was gone!" he whispered.

"That's what the note said!"

and the knob turned and opened.

"Don-na..." Clark said discouraged, as from the room stepped Korriand'arr, Princess of Tamaran.

"Oh!" she exclaimed, startled. "I was unaware of any beings seeking entrance to our-my, room."

"Where has Donna gone?"

"I believe she returned to her home. Now if you will excuse me, I will be off to the mall!" she said with no hint of sarcasm. "Goodbye Garfield, and neatly dressed bespectacled man!" and she skipped off down the hall.

When she was out of sight, Garfield whispered to Clark:

"she didn't lock it."

"Garfield, stay outside."

"but-"

by then, Clark had entered the room, and left Beast Boy outside.

"stupid adults, they get to have all the fun..." he muttered.

Clark was using all forms of vision to search the girl's room for clues. And then he saw it, a pen on a writing desk that had fresh fingerprints on it. Donna's fingerprints. And a notebook with a page torn out. She had written something here.

And so, using many science-y methods, Clark came to decide that Donna had written a note, in addition to the one on the door, which she had placed near Korriand'ar's head. And Now, to find Dianna, he would have to find Donna, by finding Korriand'ar. Of course he knew where she was, but now he had to find out why.

That morning...

Kori's snores popped and fizzled and she woke up. She mumbled a bit, and sat up. In the process she heard paper crinkle. She picked it up and turned on her bedside lamp.

Kori,

I'll be back as soon as things get sorted out. I'll tell you why I'm gone when it's okay to. Stay calm, and don't look for me, because I'll be back.

-your BFF,

Donna!

Now...

"Oh! Hello again neatly dressed, bespectacled man! Fancy meeting you here!"

"I need to find Donna, where has she gone?"

"I do not know exactly where, but she has returned to her home."

"so, I can't find her, because she's on Themysclya, and I'm a man."

"yes!" she replied with her usual cheer.

Clark was feeling hopeless. He let his head fall to his hands, he sighed. Got up and started toward Metropolis.
