When Peter is drugged, or thinking really really hard about something he often ends up muttering incoherent sentences made up of a scattering of words from all of the many languages he knows. The first time it happened was when he was super high on painkillers because they’d got his dose wrong when trying to make special ones for his metabolism. All of the Avengers were surrounding him and he started talking in what sounded like gibberish, but Natasha could make out most of it, and it sounded like he was just babbling about how he felt like he was floating on a cloud, and that clouds are really soft, and he thought they’d be colder, and… the weird part though that really drove it home was that neither Natasha, Bucky, or Bruce could make out all of it and they were the three that knew the most languages. The second time it happened was at 2 am when Peter was studying for finals in the dark (because his eyesight got enhanced with the rest of his senses and I feel like it’s skipped over too much) and he just about gave Steve, Tony, and Bucky heart attacks. They walked into the common room after a really late night session of improving Bucky’s arm (they did that sometimes when none of them could sleep) and they just heard someone mumbling to themselves incoherently in the pitch blackness. It freaked them out enough that Tony deployed the gauntlet from his watch, Bucky got a knife that was hidden god knows where on him, and Steve got into a fighting stance. When they turned the light on to see a figure dressed in black hanging from the ceiling they all instinctively attacked, Tony fired a blast, Steve threw a punch, and Bucky threw his knife. The creepiest part though was that Peter (because they realized it was Peter almost immediately after they all attacked) dodged both the punch and the blast from the gauntlet, and CAUGHT Bucky’s knife all without looking up from or dropping his textbook. He then threw the knife over their heads (because he knew who they were and he didn’t want to hurt them but seriously he was trying to study and they needed to leave) and it landed directly in the middle of them only a couple inches from their heads, at which point they ran back to the lab and didn’t come out till morning and tried to never speak of it again. But Peter secretly had Friday send him a recording for future black mail.
