Whenever Pietro was bored, he would mess with people. You and his sister especially.

You were just sitting on the couch in their apartment when suddenly you heard his sister, Wanda, shriek from the bathroom. "Pietro, I swear to God! I'm going to kill you!" Her voice echoed through the bathroom before she stormed out wrapped up in a towel with her hair wet with... oil? "You switched out my shampoo!" She yells at Pietro who is innocently sitting on the other side of the couch suddenly.

"What did I do?" He asks coyly as he uses his fist to prop up his head. She continued to lecture him on and on about how immature he is but all he does is roll his eyes and slide over to you on the couch, wrapping an arm around the back of the couch where you are.
