I’m still salty about the fact that all adaptations could have involved a scene in which Winry is working on some tall guys automail, to Ed gets really jealous about, but they all chose not to.
Edward and Winry’s oldest looks just like Ed, but takes more after Winry. He falls in love automail, is a total momma’s boy, and plans on taking over the Rockbell business whenever Winry retires. Winry is more than happy to have him as an apprentice in the meantime.
Ed is fine with it, but gives his son a hard time whenever they gang up on him, and often (playfully) complains about how his own son has betrayed him by being too much like his mother.
Occasionally, however, the kid shows some Ed-like tendencies.
Once, Ed’s automail broke while Winry was out of town, and she came home to find that their son had patched him up in her stead. The immense pride she felt was of course immediately replaced by horror when she learned that their son had not only fixed his father’s automail, but had also “”enhanced”” it with “”””sick”””” decorative attachments, as well as bright red and black flames that “look like tattoos, but way cooler”. Ed adores it. So does his son. Neither will allow Winry to change it (try to stop her, boys).
Winry worries for the integrity of the Rockbell name, and attacks Ed with a wrench. (“What about him??” Ed asks, referring to his son, who committed the sin in the first place.
“He’s your son,” Winry tells him, “his sense of style is your fault.”)
