I have a feeling that the doctor is on Rigon's side and that big box the “apprentice” is carrying is to carry Haon in for kidnapping purposes. This is all just speculation
Rigon probably is planning to climb rank then kill the boss or ruin the alliance from the inside out. My assumption because he isn't leaving the alliance but still wants Haon's trust
I was thinking that he reminded me of a pup with the way he was sitting infront of Haon. Then he was drawn as one as well, glad to know that I got the vibe right
