Here, off the top of my fucking head I'll write a better set up for this story.
Augustus, whose taken into Lucy's home for a better life- a known gang-member has a hard time quitting old habits. He hangs out (secretly) with other 'bad kids' under the bleachers, maybe they sell weed to kids or smoke cigs/drink or whatever.
He hides it from Lucy, while putting on a good-boy act. This gives him layers. But more importantly, muscle for the next set up.
(Lucy can fuckoff with Jordan or Sue or whatever sometimes)
Augustus approaches Mike, cornering him alone with his new posse, then begins to needle him with questions - then threats. He has a new 'sort' of gang to back him up. This increases the tension for Mike and makes Augustus seem more unpredictable still. He hasn't completely turned over a new leaf, because its hard for people to change. He's been a gang member since he was 11/12 or something?
It's a classic set up, harkens back to typical high school bully tropes and gives Augustus something to do besides have his head inside Lucy's ass 24/7. He threatens Mike because Mike is threatening his happy home life by triggering Lucy.
I think that is more in character then him randomly acting nice and talking to James about an obscure movie director.
