1. none of the sound's four are jounin level.
2. kimimaro *might* be jounin level. but we don't know that yet. then again, we can speculate that he's real strong since tayuya (who is actually a pretty decent ninja) is deathly afraid of kimimaro. also, someone like tayuya wouldn't let someone get away if they threatened to her life. so, i'm guessing kimimaro is around jounin level.
3. gai is an idiot. someone as clam and collected as kakashi would've just been like "eh, lee gets some what rowdy when he drinks" and ended it there instead of going "OH MY GOD, WE'RE ALL FUCKED LEE IS DRINKING HOLY SHITFUCKSLAKEKLALIDJOLWIAOJDOHIAHDIDYHAKEI'MSTUPID !!!" personally, i think lee drinking and going crazy is overrated. i'm sure he goes berserk, but not enough to cause TOTAL DESTRUCTION as gai is making it out to be.
