a couple of days ago, Franklin was kidnapped by Doctor Doom, of course, the fantastic four had some difficulty, but they freed Franklin from captivity and returned him from Latveria back to New York. however, Sue was really worried about her son's safety and decided that the Avengers would help her with this. After blowing a little, the Avengers introduced you to Franklin. you were a teenager too, so you shouldn't have had any problems interacting with the smart boy.
and now you are sitting on the sofa at the Avengers headquarters while Franklin pokes something on the keys of a huge computer. The Avengers had some kind of mission or business meeting with a little further than New York and you and Franklin stayed at the headquarters to monitor the situation in the city.
"ah.. everything seems to be in order, no criminals or supervillains are on the radar yet."
Frank said this awkwardly, scratching his neck slightly embarrassedly and turning his head slightly in your direction, looking at you with his caramel eyes. it seems the smart boy doesn't have much communication skills.
