I'm pretty sure that JARVIS can do anything and after all if Nat is a Demigod they probably heard her swear in Ancient Greek so he would have some idea of what Ancient Greek was supposed to sound like.
Sorry for the OCCness
Frank POV
I had never seen Annabeth this mad before out of all of us she was always the one who planned, used logic to solve problems, and kept her emotions in check but this, this was insane she looked as if she was going to murder some one. Percy held her back trying to calm her down it it obviously wasn't working as she kept on squirming trying to escape the tight hold Percy had on her. Stark backed slowly away from Annabeth muttering under his breath "What the hell ? What the hell?" Annabeths face started to pale as Stark kept talking. This was really bad, we all knew what happened next.
Percy POV
I held Annabeth in my arms hoping to stop the flashback before it took hold of her but Stark wouldn't shut up. Just as Frank and Piper lept at Stark, probably trying to shut him up,she let out a bloodcurdling scream that must have woken the rest of the Avengers as they came running in weapons had been really stressed out lately ,the numerous responsibilities she had were starting to take their toll."PERCY! Don't leave me! Stop! NO!" She broke down crying as I held her in my arms trying to snap her out of it "It's okay, we're safe. I've got you,I've got you." I repeatedly whispered the calming mantra into her ear and eventually the sobbing slowed to a halt while the Avengers stood around looking perplexed.
Piper POV
Since Leo was backed into a corner, Frank was keeping Iron Man from freaking out and Jason was no good at explaining things like this, the duty of explaining what just happened fell to me. Captain Americas friend was the first person to break the silence "What in the world was that?" I took a deep breath, now was clearly not the time to explain as Annabeth was a mess and it was already ridiculously late. "We'll explain everything in the morning when everyone is calm and awake. Now back to bed everyone." I allowed some of my charmspeak to leech into my voice. As everyone turned and walked out Percy stood up carrying Annabeth in his arms and walked over to the couches. I guess that the beds in their rooms were not big enough for both of them and everyone at Camp knew that they had to sleep together because of their nightmares.
