Katelyn/Affiliation

Aphmau
Katelyn and Aphmau are good friends from what it seems from The Minecraft Diaries Side Stories and The Second Season Of Minecraft Diaries episodes.

They didn't have a really good relationship in The First Season of Minecraft Diaries. Aphmau and the other guards thought that Katelyn was a spy sent by Zane and they started to feel uneasy having her in Phoenix Drop, and tried to reject any invitation from her or any of her gifts.

Before the battle between Phoenix Drop and The Alliance with O'khasis and Scalewinds, Katelyn became a guard of Phoenix Drop and she started to be pretty protective too! for example on The Second Season of Minecraft Diaries on Ep.17 when She and Aphmau where trapped and the Wolf started judging her and Aphmau she went berserk saying:

"I DEMAND TO KNOW WHERE WE ARE! YOU BETTER LET ME AND MY APHMAU GO OR ELSE IM GOING TO!"

On Minecraft Diaries Side Stories they are really good friends and looks nothing more than that, but Katelyn did mention on Minecraft Side Stories Ep.3 Autumn Minecraft Roleplay  "You guys think you're shocked? i just caught Aphmau cheating on me."

Other examples:

Minecraft Side Stories Ep.1 The Big Misunderstanding

"M-M-MOVE!? YOU'RE MOVING!? HOW COULD YOU! AFTER EVERYTHING WE'VE BEEN THROUGH TOGETHER! YOU DON'T THINK I JUST WANT TO MOVE SOMEWHERE WHERE I CAN FOCUS ON MY MARTIAL ARTS TRAINING!? BUT I CAN'T WE ALL MOVED HERE TOGETHER! YOU CAN'T LEAVE ME ALONE IN THIS WORLD APHMAU!"

Laurance
Katelyn thinks Laurance is a great person, showing concern when he starts acting strangely and gets along with him well, and it's possible Katelyn has feelings for him.

First ever hint : ''Minecraft Side Stories Ep.1 Slumber Party. "Pardon me for saying this but..Laurance triumphs them all.''

Minecraft Diaries Second Season Ep.16

Aphmau: "Are you going to be joining us after all?"

Katelyn: "I will. Is...Laurance going with you as well?"

"Minecraft Side Stories: The Big Misunderstanding"

Katelyn:"I kind of figured out you'd go for Garroth or..um Laurance.."


 * Kawaii Chan has shipped Katelyn and Laurence, revealed in The Big Move Side story.

Vylad
In Q&A question Vylad recieved. question from one of his fans. The question asked, "Do you mind getting shipped with Katelyn?" Vylad answered with "She is cute ." But they don't meet quite regularly. To support the said theory, she said something in Minecraft Diaries that she trips on Vylad and he pick her up, she looks at him straight in the eyes. She said that he looks like Jeffory, which is true.

During "Spa Day," Katelyn confirms that she may have an attraction to Vylad, mainly due to his green eyes. This may be due to her close friendship with Jeffory, who also had green eyes.
