as a leader he should at least know how to handle some weapon types, firearms and some melee weapons, he knows how to use a baseball bat already, swords don't fit him tho. at least in my eyes, he doesn't hate "it" to use the sword, Saeko on the other hand, mmmm, fits like a glove.
I really liked how he stopped Saya talking just then, she really showed her bad side in this episode, not that I blame her, it was pretty much the same in the manga too, Alice said something really interesting didn't she ? she isn't just a silly little girl anymore, looks like she adapted to the new situation a little, or a lot, I think a small firearm would fit her, maybe a hunting riffle, or something, dunno, she will have to use a weapon eventually, i wonder what it will be ;]
