Lincoln then made his way downstairs, seeing his mom and dad on the couch, watching some sort of judge show.

"Hey, Rita? Lynn Sr?" Lincoln quietly started.

"What is it, sport, and why did you call us by our real names?" Lynn Sr. replied.

"Well, that's what this is about. remember that family I thought was my real family?" the white-haired boy asked nervously.

"Yeah. What about them?" Rita said, a little confused.

"I'm still a little skeptical on if that family is mine or not." Lincoln said.

"But Lincoln, we gave birth to you." Lynn Sr. reassured him.

"I still wanna find out." Lincoln moaned.

"Lincoln, believe us!" Mr. Loud begged.

"Rita, can you call them?" Lincoln asked his mom in determination.

"Well, I guess we will do this for you." Rita said.

"Okay." Lincoln cheered.

"But, how will we reach out to them?" Rita asked.

The middle child then pulled out their phone number written on the notepad he and Clyde used while inspecting families.

"How'd you get this, son?" Lynn Sr. asked him, stunned and confused.

"Simple. We used cameras." Lincoln told the two.

"Okay, we will contact them." Rita promised Lincoln.

"Got it!" Lincoln replied, and he went upstairs.

Rita dialed the exact number and put the phone up to her ear.

"Hello?" said the dad Lincoln thought was his.

"Oh, hi." Rita replied.

"So, why did you call, mate?" the man said.

"Well, we have a child named Lincoln Loud. He thinks that he might be part of your family, as he has white hair like you." Rita said

"That's crazy! He has white hair like us? Cool! Me and my wife have white hair, too!" the man complimented.

"Yeah, so I was wondering if you could meet us at the Royal Woods DNA laboratory downtown." Rita suggested.

"Well, sure. Despite how ridiculous that kind of sounds, we'll be there." the man promised.

"Good, see you there tomorrow." Rita said.

Rita then hung up.
