keep your heart around (you might need it someday)
Tony Stark finds himself as a de-aged Loki Odinsson's temporarily designated parental figure, through no fault of his own. Responsible superhero co-parenting doesn't just involve feeding, housing and clothing a tiny Asgardian, it involves rubber ducks, transdimensional vortexes at bathtime, fruit parties, pictures of robots that draw other robots and hoverboards (eventually), as the team keep Loki safe while they look for a solution.
