They didn't make her overtly racist because it's a slow burn for the people who didn't read the comics or the spoilers. The fact she blasted through about 10 black civilians should also leave a bit of an impression. People will probably think she's wreckless or was upping the "terrorist damage", but I imagine in future episodes it will go out of the way showing her saving white KKona civilians or something.
The Deep and/or Homeland should win an emmy for their performances. Just fucking great. The Deep honestly plays his character so fucking well. I had no idea who that dude was, but he's going to get some bigger roles for sure. And Gus Fring is pretty good too, but he just seems to be more Gus Fring.
