Okay, so this really bugs me. In the next few pages, I should have drawn Roka with a holster on the back of his vest belts. Obviously he’s had his gun on him the whole time he’s been in the city station, and since he hasn’t been carrying anything with him, it had to be on him. Up until now, you only see him from the front or side, so it has to be on his back.
On the next couple pages, you get some clear views of his back…and no holster. Which means he whips the gun up out of thin air. It’s a very minor detail that I’m sure no one would ever notice, but I generally try to be careful about those things, so it does bug me a bit.
