nah dude its cool, shoryu put them their for you to interact with them. the story is based around us and what we do, there is no set path really. so do whatever you like interact with whomever. although since it is a named guard id leave their response to you to shoryu, but you are free to control a few nameless guards if you like. You do have a tendency to make all nameless characters you interact with extraordinarily mean, and i believe the senior guards already have a chosen personality, so yeah unless you want to act out the convo with shoryu over skype then i would leave the response alone
