To add on to this, he even says "fuck.." when he shoots the other hound, meaning he actually wanted to kill him. question is, how tf did he manage to avoid getting seen by guwon while running to kill teach. This makes me feel very suspicious about sangjun. What if he's with red head and also wants to kill teach. We can't forget that the hounds do worship guwon, and teach is just another liability and threat to them.

There's just no way the Yeonghyeon shot like that cause he was trying to protect teach from a hound that was trying to push him, he literally hates his guts, this was intentional, he even yells out "get down!" Before he does, cause he knows the hounds r alert to these calls and would def get down when hearing that vs if teach heard it, leaving him the only one standing up to clear him a perfect path to shoot at him. He WANTED to shoot teach
