"Look, Soph. This should be the surveillance room." Alex said as he came in, followed by his sister. "We can see the whole hotel through these screens."
"Let's see..." Sophie said as she watched looking for something interesting. "People everywhere, at pool, beach... shops... It's not that interesting as I expected it would be..."
"You can find something interesting if you watch carefully." Alex said while he kept watching through the screens. "I've seen several potential victims for pranks like that old man at the lobby or that couple at the pool. I've even have seen a lot of places to hide. This information is pure gold!"
"Boring..." Sophie said while she looked what else she can find in that room. "Hey, Alex. Look what I've found in this locker!"
"What?" Alex asked while he turned his head to her sister's place. "An old... uniform?"
"It seems it belonged to a security guard. What do you think if you try it on?" Sophie asked while she extended the clothes to look at them better.
"Why would I do that?" Alex questioned as he approached her. "Also, that thing looks huge I will look ridiculous wearing it."
"That's the point." Sophie smiled. "Please, do it and I won't ask you for anything else during this vacation. Please!"
"Ok, fine. But I won't take my clothes off. I'll just put these on, you'll take a picture or whatever and that's all!" Alex said while he started to put the oversized pants on. He was wearing sandals and swimming trunks, so it was quite easy.
"Thank you, so much! Mom and dad will love a goofy picture like this!" Sophie cheered while her brother put the shirt on over his tank top. The clothes looked comically huge on him. It seemed he was doing the superhero pose but in fact he was trying to keep the pants on.
"Quick. Take the picture!" Alex ordered and Sophie can notice he was a little pissed off. So, she quickly took her phone and started to take some photos. However, she noticed that something weird was happening. A blue aura was surrounding her brother. It was strange but she thought it was just her imagination or the screens lights.
"Woah! I'm feeling... dizzy..." Alex said as he put a hand on his forehead. He didn't notice it but Sophie did that his arms were swelling at an alarming rate until his biceps were constraining the shirt's sleeve. "Huh? Whoa!!" Alex shouted surprised while his other arm swelled to bodybuilder proportions.
"Alex!!" Sophie ran to help him but a sudden blue energy blast came out of him that pushed her away and making her unconscious for a few seconds. When she recovered her senses, her brother wasn't there anymore. In his place, a huge manly version of him was there panting like he desperately needs some air. "Alex?"
"Huh?" The man had a way more deeper voice than Sophie's brother. "What are you doing here, young lady? This place is staff only. I need you to leave immediately."
"Wait, Alex! It's me, Sophie. Don't you remember me?" Sophie tried to tell him while she was crying desperately. "You're scaring me!! Please!! This joke isn't funny!"
"I'm sorry, but I'm not joking. If you don't cooperate, you could be banned from the hotel permanently. So, I'll ask you one more time. I need you to leave immediately."
