Interesting how people are bringing up Fitzsimmons family headcanons.
Just sharing: It’s the same for me that Simmons is probably an only child with loving parents and a great childhood. But for Leo, his mother is either tremendously sweet or has passed away, and he doesn’t get along with his father, has been estranged for years, and Simmons is sure that that’s why he has such a temper.
What’s everyone else’s?
I imagine Leo’s background a lot like the way I image Topher’s from Dollhouse. He was so brilliant from a young age he ended up isolated from all the kids around him, who made fun of him or bullied him. His parents weren’t necessarily bad people but they didn’t know how to handle Leo (their only child) and sent him off to some really prestigious boarding school when he was really young. They never went to visit him, but they sent birthday and Christmas cards and called every once in awhile. When he arrived at the Academy, he found Jemma and she became his makeshift family, though he would never say so out loud. His current relationship with his parents is just a stilted and kind of formal call on holidays. I imagine Jemma went to boarding school as well, but because she wanted a more challenging education and asked her parents to send her. She mostly got along with the kids around her, even though some were intimidated by her and would make fun of her behind her back. She had an easier time letting that slide off her back than Leo because she had so much support. She was also an only child and still has a great relationship with her parents, though they don’t get to talk as much as the used to.
