FOUND in comments. Thank you!
Could someone please help me find a fic I read a while ago where Peter found and fixed Jarvis as a gift of some kind for Tony. I think it might have been for Tony's birthday or for Father's Day. I'm also pretty sure that Rhodey knew about it. This story definitely didn't have Harley in it. I could swear this story exists but I can't seem to find it anywhere.
Thanks in advance for any help!
