As it turned out, Damien has a superpower that can change sizes at his own will, but why didn't his brother nor his mother tell him this in the first, so this may be his first chance to find some answers, while still shrunk down at 5 inches. Once he saw a giant looking Kyle about to head his way out of the bedroom, it made Damien with no hesitation but to try and yell out as loud as he could, so he could try and get his older brother's attention.
"Kyle! Kyle! I'm down here!" Damien yelled so loud, it actually caught Kyle's attention almost straight away.
At first, Kyle looked a bit confused to hear that voice in the room, which he doesn't seem to recall seeing someone in Damien's bedroom when he's in. But then just as he turned himself around and then looked down from the sound of a voice, it had taken himself by surprise just to see his little brother now looking so tiny, this is actually the first time he can see a shrunken Damien in person, and that's when he's at awe and reacted by crouching down to give a closer look at his little brother.
"Oh wow! I didn't realise you're so tiny when I came in. Otherwise, I would've stepped on you without realising where you are." Kyle's voice boomed in echoes, as he actually blush just to see how cute Damien looks in his 5 inch figure.
"I know, I just figured it out until I woke up." Damien replied just by looking up at Kyle in awe, before he asked him a question that he needed to know. "But I've heard from you saying I have a superpower that can change sizes. Why wouldn't you or Mom tell me about this before?"
That's when Kyle had a curious smile, as he gets down further and picks Damien up in the air, which is hard to believe that it's like a toy he's holding when he was younger, and it got him flashbacks about it. As far as Damien's view, he didn't expect to get picked up from his brother, which made everything so intense, especially when he was in the air and had to look down at his bedroom looking way higher than usual, because of his 5 inch height alone.
He was a bit shaken that everything is new to him, even when he's hanging in the air while picked up by Kyle's fingers, and it wouldn't be long until Damien was brought to his brother's face that looked so huge, it made the tiny boy blush with a bit of nerves, but claimed things down as he heard from Kyle trying to answer the question of keeping Damien's powers a secret until now.
"Well... It was a secret between me and Mom, and as for why we didn't tell you this before, I think..."
