Since you guys have been so patient with me, I decided to draw/color all the Zinc wives, which include two I've never drawn/posted before (and I never colored Isabelle before, either).

A few things before I talk about each one specifically. Zinc wives sort of have their own set of rules. First, all Zinc wives have a strong desire to kill Flint (except the first one, since she knew him as a kid and Flint acts a lot like Isaac [since she's Isaac's wife]). This is mostly because of how aggravating Flint is. It's been scientifically proven that only sane women want to kill Flint, as insane ones are more likely to like him.

Second, the Zinc child will inherit the mother's main personality traits and manner of speech. While the father gets all the genetics, it's quite rare for a child Zinc to be anything like their father personality-wise. They tend to lean more towards their mother in that respect.

And third, every Zinc wife is responsible for the Zinc child's main talent. For example, Kate is a very well known scientist, and this led Jasper to become one as well. The wife on the far right is a conductor/musician, which is Riley's main focus and talent.

So now, the wives, starting from the far left:

Thursday Zinc
Isaac's wife. She may appear to be just a humble butcher, but that's just her cover. She's actual a criminal, and often helps Isaac with his more "morally challenged" tasks. She's very blunt about everything, much like Dominic. She just never gets caught because no one ever thinks to just ask her if she's responsible for all her underhanded crimes.

While she doesn't really do any of the more violent crimes like Isaac sometimes does, she is a notorious thief (which is what leads Dominic to his pirate line of work). In fact, she buries a lot of her profit she's stole, which Dominic used to go dig out for her when he was young.

And while she's normally not violent, she's not at all shy about using that knife of hers on someone if it calls for it. She's a great cook, though.

Kate Zinc
Dominic's wife. Considered to be one of the brightest scientists of her time, Kate is known throughout the science community (for her knowledge, insight, and all the nerdy scientists can't take their eyes off her). In fact, there are multiple posters of her around Arsenic Labs hung by other employees (Arsenic himself doesn't mind them since Kate's the only woman he's ever found attractive, and Jasper thinks it's unsettling).

She's quite clever, and she knows it. She's got a bit of an ego, as she can't resist the urge to prove someone wrong in an argument and shove it in their face. Kate has a very short temper, too. She actually met Dominic when the two got involved in a bar fight (with each other). After kicking each other around for a bit, they decided to get a drink together.

Kate is someone to never cross. She holds grudges for quite awhile. Her field of study is in cloning, along with a few other things that are spoilerish.

Isabelle Zinc
Jasper's wife. A very warm, friendly girl, Isabelle is exactly what Jasper is not: a social butterfly with a level head. She's the one that keeps Jasper in line to keep him out of trouble, and the one that gets him to step outside the lab every once in awhile.

Isabelle's rather bubbly, and especially loves socializing. In particular, she enjoys talking to children (she works for a daycare). Due to this, she has boundless energy and could run circles around Jasper easily in terms of physical activity.

Elizabeth "Lizzy" Zinc
Cyrus's wife, who died giving birth to Riley. She's a music conductor, and also plays the piano. Lizzy is a little shy and nervous around people, especially those she doesn't know. It helps to have Cyrus around to break the ice for her and drag her along on adventures with him (not to mention help her relax every once in awhile).

When she gets involved in anything musical, though, she blocks everything out and just focuses on the music. This is the only reason she can perform well in front of an audience; she forgets they're even there.
