I Can't believe you've done this

Holy shhhh, you're british?

One month ago, one entire month ago something horrible started. A vine war. Tony was getting angry that Peter was teaching everyone in the tower vine references, and it was getting annoying. So he told him to stop. But Peter only said he would if someone in the tower could beat him at a vine war. You start the vine and the other has to finish it. No. Matter. What. The only other rules were that if there was an accent you had to do it, and after you do the vine perfectly you had to had on. And it has to make since. Everyday tiny tried to beat Peter. Everyone did, but none succeeded. So a month later when there was only Peter, Loki, and Tony left in the war, tony brought in some....backup. Shuri to be exact. And there was no rules against it.

"Shuri!" Tony called out as Shuri left the private Wakanda plane. She looked beyond excited and dare I say, giddy?
"Hello Tony!" A mischievous smile plagued her lips. She already had a plan and tony knew it would be a good one.

"Wait, this is your master plan? To just smack him and hope he can't think of anything?" Tony stares down at the Wakandian princess.
"Well, yeah! Trust me, Peter not only hates that vine. But come on, Peter and a British accent. If anything he'll fail at that."
Tony pinched the bridge of his nose and released an annoyed sigh. "And you couldn't have told me this over the phone why?"
"Well I wanted to be the one to smack Peter. Duh."
Tony just stared at her, and just walked away into the common room. Where everyone was sitting and watching a movie. Peter perfectly placed on the arm of the couch. Tony gently sat down next to him and muttered under his breath for Friday to start recording. "What did you say Mr. Stark?"
"Hm? Oh nothing." Peter said nothing and refocused on the show. Then his eyes went wide as Shuri came in. She walked with a purpose and straight up to Peter. "Shuri! I-" Her hand connected with his face and a loud smack was heard. Everyone held their breath and prayed that Peter would finally lose. But their prayers went unheard because without missing a beat Peter started with a flawless British accent. "'Fruitloop' I can't believe you've done this...I trusted you Shuri and you just betrayed me. Now I can never trust you again. I-I thought you were on my side!" Peter laughed and looked around at everyone's dropped jaws. "Dang it." Was all that was heard from both Tony and Shuri. "I thought you said this would work Shuri!" Tony shouted.
"I'm sorry I didn't know he could do a flawless British accent!" Shuri screamed, matching his voice.
"Well, technically I don't do a British accent, I do Queens accent." Peter corrected. Everyone who was previously watching Shuri and tony bicker turned to stare at him. "Peter, what does that mean?!" Steve asked bewildered.
"Well you guys do realize I'm British right?"
Everyone just kinda dropped their jaws.
"What!" Tony screamed. 'Cause Tony knows his surrogate son really well and never once has he mentioned that he was British.
"Yeah, umm when I was six I moved to America and then when I was ten and met Ned I dropped my accent." Nobody said anything.
"Holy shh, you're British!"
