New Character Roundup and Poll

With all the new casting calls and character info being released recently, I thought it would be a good time to roundup them all up and see which ones you are most interested in and if you have any speculation/thoughts about who they might be, who they work for/are related to etc.

[Abigail] : British woman in her 30's. (Theresa's nurse)
[Casear] : A dangerous, physical and extremely intelligent male between the ages of 35 and 45. Although his intentions are unclear, this much is certain: he's as skillful at charming people as he is at killing them. He also has a dark past..
[CUNNINGHAM] : Mid-20s to Early 30s. Any ethnicity. Athletic, used to living outdoors and off the land. He is a loyal soldier but willing to compromise with the enemy to protect his men...VERY NICE CO-STAR. THIS ROLE IS INTRODUCED IN 502 AND HAS 3 SCENES IN 503.
[DAN] : 40s, any ethnicity. A high-priced attorney, someone really sharp who can be friendly. However, there's a real menace lurking below the surface. RECURRING GUEST STAR
[DARLENE] : Early 20s, any ethnicity. A bored clerk who hates her sucky job and looks for any burst of excitement to get through the shift. Alternative in dress and style, plays guitar in her own band but needs the day job to pay the bills...CO-STAR.
[FOREMAN] : 40s to 50s, any ethnicity. A blue-collar construction worker. He's worked hard to get where he is and provide for his family. He cares deeply for his crew, hates it when management is condescending and arrogant but ultimately knows his place in the pecking order. CO-STAR.
[JILL] : Late 20s to late 30s; any ethnicity. A butcher who is one hard-as-nails cool chick. A tomboy, bit of a searcher, and highly competent beyond her station in life...CO-STAR.
[Ilanna] : a European female in her late 20s to early 30s who possesses great intelligence, but who's also dangerous as all get out. She's alluring and apparently used to getting her own way.
[MARTHA] : 35 to 40, Asian, attractive. A smart, capable scientist with a strong personality who has taken a break to raise her baby but plans to work again. Completely believes in the work she is doing but sometimes questions the decisions of those in charge...CO-STAR, RECURRING
[Nigel] : British, in his late teens. Smart and mature for his age, if a little rough around the edges.
[Sophie] : British aristocrat in her late teens and appears quite innocent and a little prim, but underneath she is formidable.
[Theresa] : British woman in her 30's. Suffers from dementia.
