He certainly is...
He is not. X is X, Boston is Boston.
I'm just a newbie in Masters, so I can be wrong, but my impression is:
1) Do Masters tolerate bad behaviour by their clan-mates?
Masters are very tolerant, you will never experience any intolerance when you join.
2) Will X/Boston face disciplinary action?
X/Boston will face anything coming their way, they are awesome like that.
3) Will Masters bolster their recruiting process to keep out bad actors in the future?
Like I said in reply to 1), Masters are very tolerant, you do not need to have good acting skills to join (but they do help a little), alas WZ skills are quite important.
