Name: Olivia Dixon.
Gender: Female.
General appearance: The easiest way to describe Olivia is basically a miniature version of Melissa (down to the way the hair curls, the size of their fingers and body shape) but with Daryl's genes shining through in terms of both hair and eye color. Honestly, out of all their kids, Olivia is the one that is so evidently a product of their relationship that would be ridiculous to claim otherwise even if they no longer have the technology to run DNA tests.
Personality: Outgoing, lively and excitable, Olivia doesn't appear to be aware of the harsh conditions she's growing up in - but that's largely because she just doesn't know better. While she cannot miss the world she never knew, there is also some of her environment to be credited for the way Olivia is hard-working and optimistic - protected by their community and watching her parents doing so much for others (either as provider to the group or taking care of them), Olivia didn't find it challenging to be a nice or good person - it's just who she is. Having in Judith an inseparable companion and sister-like figure also shaped much of her in terms of personality.
Special talents: A survivalist by excellence, just like Daryl - honestly, she is her dad's girl and loves the outdoors, animals, learning about the world and feeling at peace while sleeping under the stars. Daryl was always very focused on teaching Olivia (and then the other kids) about the basics they needed to know to just survive out there, should the worst come to pass. Olivia can track animals (and people), set traps, kill, skin and cook game, climb uneven paths, build decent shelters and determine edible plants with quite a lot of skill.
Who they like better: Daryl, by a mile - and it's obvious. It's not like she doesn't like Melissa or as if they didn't get along well because they do - it's just that she's so similar to Daryl in so many ways that they connect on a deeper level. They can understand each other without words, go for hours on hunting trips and enjoy it, volunteer for the job no one wants to take it without making a fuss (including killing walkers) and so on. Olivia is very social and loves her siblings and community dearly, but her dad's just special.
Who they take after more: Also Daryl, for the same reasons above - although her cheerful personality and charisma is where Olivia sets herself apart. Those are generally regarded as her 'Melissa' traits seeing as how the girl will strike up conversation with anyone and is also not shy of voicing her own thoughts and opinions. Similarly to her mother, she is also protective (and proud!) of Daryl and doesn't take kindly to people badmouthing him.
Personal Headcanon: It started as a bit of a joke when she was little, but Olivia loves scavenging olive / olive oil cans and bottles whenever these are still around in abandoned homes or facilities they find along the way. When the girl was younger, the thought that these were her 'property' because they had her name on the labels was such a cute notion that neither of her parents had the heart to crush it with reality - and it just evolved into a funny, harmless hobby.
