At the living room, the Loud sisters watched as Lynn and Lincoln danced together. Lynn spun around and swung her hips while Lincoln tried his hardest to keep up with her fast pace.

"Okay Lincoln, try to synchronize with Lynn's movement," Lori instructed.

"I'm trying!" Lincoln complained in return.

And then, when Lynn hit him with her hip, the boy collapsed and hit the ground. "I think that's enough training for now, Lincoln," Lori said as she went to him and helped him get up. "Take a breather, and make sure nothing got damaged."

With that done, Lincoln dusted himself as the sisters left the room. He then sat on the couch and turned to the reader.

"The Loud House is certainly an interesting house: a large family, most of them girls with distinct-if one not-personalities and abilities," he said as the camera got closer to him. "But there's another interesting thing about us Louds."

Sometime later...

Lincoln sat down next to a birthday party, where Luna and Luan acted as the performers while the kids. Then, they performed a little dance together-where Luna thrusted to the beat while Luan wobbled around as they got closer-until they collided and turned into light, combining into a bigger performer, who shred a large guitar-dummy hybrid as the children cheered.

As for how she looked, her clothing was a mixture of Luna and Luan's, and she had long, wild dark brown hair with light brown highlights, tied in a long, messy ponytail. She also had a pair of groucho mask-like glasses.

"The Louds can fuse," Lincoln finished before gaining a somber look. "Or more accurately, almost all the Louds can fuse."

Then he look at his reflection in the drink. His solitary, lonely reflection. And then he glanced at Luana, who was basically Luna and Luan together, playing in great, bear perfect harmony.

"To fuse, a Loud must synchronize with another Loud in order to combine their bodies into one, but..." the boy paused, took a sip from his drink and then finished, "Well, I haven't been able to synchronize with any of my sisters. And no matter how hard I try, I'm no closer to synchronizing with them than I am right now-"

"Maybe you're trying too hard."

The boy flinched, then turned around to see Lucy was next to him. "Oh hi Lucy, when did you arrive?" Linc greeted, still catching his breath from the scare.

"I have always been here," Lucy answered. "Anyway, It's just my opinion, but maybe you should first focus on getting to know one sister before trying to synchronize with them?"

Lincoln then took a minute to think about it: Getting to know, and most importantly, deciding with which sister he would fuse with first, would probably help him learn how to perform fusion. It would probably take a while, though.

"Thanks, I think I'll keep that in mind, Lucy," Lincoln replied. "Thanks for the-"

But then, he saw Lucy was nowhere to be seen... only for her to return with a refilled drink. "I went to get some more juice," Lucy explained as she sat next to Lincoln again. "Anyway, what were you saying?"

"I was thanking you for the fusion tip," Lincoln said.

Lucy gave her brother a drink, toasted with him and they drank their juice in unison.
