[X] Try and get it to communicate
Robin frowned as he stared at his semblance.
Hello? Robin wrote. No Response.
[X] Try calling the shadow Blake if it doesn't respond
"Blake?" Robin said, then wrote in his journal. Again, no response.
Robin shared a befuddled look with his parents before another idea occurred to him.
I think it acts when Robin writes it's actions like a story character. Third person.
Blake stood up.
The shadow stood up.
Blake said hello.
The shadow stood in silence. It had no mouth with which to speak, something that unsettled Robin. It had no eyes either. In fact, the only thing that hinted towards the shadow being Blake was the hair.
-[x] If it lacks vocal cords, try and get it to write
Robin frowned again. Was this just something that
looked like Blake?
Blake wrote 'hello' on the wall.
The shadow turned and, in an elegant flourish ever-so-slightly off from Blake's handwriting, wrote 'hello' on the wall. Ghira and Kali looked at the shadow in concern.
"You told it to do that, dear, didn't you?" Kali said.
"Mhm." Robin nodded. "I don't think it's actually Blake. It's just a—a shadow of her. . ."
"Don't worry about it. You have a semblance now. You should be happy! Why don't you, err, play around with it for a bit? No need to help out with dinner, I can do that," Ghira said.
"Okay," Robin said. Ghira and Kali left the room. Robin felt a faint glimmer of excitement well up within in spite of his mood. It's true he didn't/couldn't bring Blake back, but maybe his semblance could distract him until his mother tracked Blake down.
-[X] If the above fails, try writing different stories about Blake to see how/if the shadow responds
"What do I do with you," Robin said to himself. The shadow stood on the other side of the room. Waiting.
Robin picked up his pen and began writing. This time, he kept the shadow firmly in his field of view. He started small, exploring how The Shadow would respond to different prompts.
Blake jumped.
The Shadow jumped.
Blake walked around.
The Shadow walked in circles. After a minute, Robin quickly grew impatient. He tried bigger actions.
Blake made the bed.
To Robin's joy, The Shadow did just that. After having had The Shadow clean his room. Robin stared at the entrance to his room in contemplation. Slowly, Robin wrote the next sentence.
Blake left the room.
Robin watched with bated breath as the Shadow walked out of the room, through the door, and out into the hallway. Excited that The Shadow was not confined to his room, Robin let his imagination run wild.
Blake teleported outside the house.
The Shadow vanished into a pool of shadow on the floor. Robin dashed to the window and watched as a the shadow bubbled forth from the ground right in front of the window.
Blake waved.
The Shadow waved. Robin waved back before he realized his folly.
Blake walked to the market.
This time, a small shop stand emerged from the ground in a pool of inky black. Robin watched as The Shadow shrank in size to match the size of the stand. Robin felt a vague sense of unease take over him. Ignoring the strange sensation, Robin wrote another sentence.
Blake saw Gilbert at the market.
A second shadow appeared from the ground, and the market stand and The Shadow grew even smaller. Robin could feel something inside of him starting to fatigue. It was a strange sensation, like he was stretching something inside of his very being. Fearing that he was overdoing things, Robin quickly scratched out his previous two sentences.
The shop and the second shadow melted back into the ground. Robin still felt the strain.
Blake disappeared.
The Shadow disappeared, and Robin sighed in relief as he felt the strain lessen. He figured he couldn't keep his semblance out for too long. Robin glanced at the clock. He'd only had his semblance out for maybe. . . forty minutes?
Over the next few days, Robin spent his free time exploring his semblance whenever he could. He found that there were some simple rules, which he had scrawled on the inside cover of his journal:
1. The Shadow goes by Blake.
2. The Shadow can't be further than fifteen feet from me.
3. I can make more shadows but they make everything smaller.
4. I can only keep The Shadow around for an hour.
5. I dismiss the smaller shadows by scratching them out.
6. I dismiss Blake by writing her away.
There was of course one more rule, but to Robin it had seemed so self-evident that he hadn't bothered writing it down: the shadows only started appearing when he wrote about Blake.
Instrumental in the codifying the "Rules of Shadows" as Robin liked to call them, was Gilbert, who had been the one who wanted to study Robin's semblance in such detail.
"Lucky!" Gilbert said when the Rules of Shadows were codified. "You're one step closer to being a huntsman! I wish I had a semblance. . ."
"Hmph." Robin rolled his eyes. "It's not like Blake's any use. By the time I finish writing a sentence, the Grimm would've had me for lunch."
"You're so wrong and you don't even know it." Gilbert leaned back in his chair, almost toppling it over. "You're supposed to use your semblance to fight
for you. Duh!"
"How fast do you think I can write?" Robin exclaimed.
"You're supposed to train. Besides, there's shorthand." Gilbert gasped. "We should totally see if shorthand works."
"I'm
tirrreeedd Gilbert."
"Fine. Fine. Fine. But you better try this out tomorrow with me. This is so cool. You're going to be a huntsman! Man I can't wait till I get me semblance. The two of us will be the pair of best friends that all the Grimm are afraid of."
"Hah. . ." Robin laughed, though the sound came out forced. To be honest, as excited as Gilbert was about the two becoming huntsman. . .
Robin:
[] Didn't want to be a huntsman.
[] Wanted to be a huntsman.
