Thankfully Xemnas is amazingly not prone to violence unless provoked a lot. And he's not really a rude or bad tempered guy. 8( ..Which isn't to say that the warning thread isn't EXACTLY RIGHT, just he's a lot less inclined towards being randomly evil with no reason, unlike quite a few villainy-types. Be pleasant to him and he returns the favor unless actively being harmful is more beneficial. So in theory they should be okay!
