Some notes on Donnie:

- He's well over 250 years-old

- Outside of holofilms and dictionary definitions he's never seen a toilet before. He instinctually finds them gross and unsanitary

- Has a penchant for exploring the inner workings and outer bounds of his vault, "sneaking" through the maintenance tunnels & outer structures while accompanied by his mommybot (Cynthia)

- Has a strong interest in computers and machines. Whenever a mechanical or software issue presents itself he's the first person that others look to for help

- He used his tech knowledge to develop a new Pip-Boy, the "3049". It added a new panel with extra keys in order to better facilitate playing computer games (useful for when the kids wanted to stay up past their bedtime)

- Developed dozens of computer games and frequently collaborated with his friends to make their game ideas a reality (an activity that made him favorable in everyone's eyes)

- He's never needed to truly lie in his life so he's awful at it

- Is a bit of an amateur photographer and always carries a camera with him

- He's nearsighted, so he needs to wear glasses

- His favorite drink is Atom Dew

- His favorite food is Cherry Jello

- Cannot go to bed without his sock monkey "Obo"
