Cooking up some headcanons for Dizzy to give her a bit of zest and spice.
Dizzy can be presumptive and even judgmental of others. It's a flaw she's actively working on, but it can be difficult for her to shake off her personal deductions and pick up the truth. She began to develop this bad habit of hers in her youth. When she was a little girl, she was judged constantly, so she began to adapt to the world around her, and judge others as well. It doesn't help that she grew up around older and likely more conservative parents as well.
Dizzy isn't necessarily religious like Ky, and she doesn't really identify as Christian like her son and husband. However, once she's settled in Vialattea, Dizzy does find enjoyment in going to church. Attending church service is something that she finds stability in, and she does appreciate being amongst like-minded gears and gear hybrids. She always pencils in church socials in her calendar.
In relation to the first headcanon, Dizzy can be emotionally immature at times. While she's very empathic, she often expresses it in a shallow way. This is because she's just not that worldly of a person — she spent about two years of her relatively short life in suspended animation, and hasn't been able to travel as much as she'd like.
When Sol retired from bounty hunting, Sin started inviting him over to visit him and his family. As a result, Dizzy began to see Sol a lot more. However, much to Sin's dismay, they actually butt heads a lot. Dizzy is far too much of an optimist in his opinion, and Sol is far too aloof and irritable in her own.
