"You heard me! The character known as Sheik is none other than Zelda!"
Oh, hello there. Looks like I went back in time to a video game called Hyrule Warriors so I can fix this shi... Oh, language. In this game, swearing isn't allowed. The reason I came here is to fix this little plot hole in Legend Mode.
The plot hole is that Zelda came to the group in a disguise and she calls herself Sheik. I get that she's trying to protect her friends, but look at the fu... bad things that happened with it. Her own forces demoralized and Impa here has no trust in her.
In three words: Worst. Decision. Ever.
Good thing I'm here to fix this.
"Do you have proof of this claim?" Link asked.
"Oh, you'll have your answer right from her lips," I suggested to have the princess admit the truth here.
"Are you insane? If you all know the truth, then you have doomed yourselves!" Zelda defied my expectation.
If she won't talk that easily, then there's only one option.
Violence.
I pulled out my gun, and I shot Impa to her leg. I'm sure that's enough to get Zelda horrified of what I just did. Aftet all, the former is her bodyguard.
"Impa!" Zelda, along with Link and Lana, exclaimed.
"Tell them the truth, or my next shot will kill her," I aimed my gun to Impa's head to make my point here.
After a few seconds...
"Alright, you win! I'll tell them the truth!" Zelda gives in to my demand. "Just don't kill Impa. She's my friend, my closest friend."
"Closest friend? So it really is you, Zelda," Impa realized. How stupid could she get? Why couldn't she just figure it out early on when Sheik showed the Triforce of Wisdom on the back of her hand?
Anyway, the princess starts telling the truth to her friends of her reasons for disguising herself as this Sheikah warrior they see before their eyes.
Just to be clear, I hate long-winded explanations. To me, they're just boring, so I'll just fast forward to part where she finishes her explanation. What she told is entirely your interpretation.
"So that's my reason for disguising myself. I thought I was protecting you all, but all I did was made you all worry about me. Can you ever forgive me, especially you, Impa?" Zelda said.
Just then, Link, Lana, and Impa hugged her.
"Of course we forgive you, princess," Impa smiled.
"I must admit that you had us all fooled. No hard feelings on that," Link reassured her.
"It doesn't matter how you look on the outside. All that matters is that who you are on the inside, princess," Lana reassured her as well.
"Link... Lana... Impa... thank you," Zelda smiled on how lucky they forgive her for this deception.
At least that solved the plot hole in this game.
