And there it is, the question Stanford knew his brother would ask, yet still hoped in vain that he wouldn't. He visibly recoils when Stan looks up at him, his shoulder's hunching as he averts his gaze and drags a hand through his hair.

"...I told you, Stan, I've made a lot of enemies here."

That's as close to a direct answer as he's going to give; not that Stan likely needs the clarification. The fact that he refuses to meet his brother's eyes or give a solid, definitive response to his question says it all. His lack of an answer is an answer in and of itself.
