Raikaria's crazy theory is that we should sniff every person for the scent of potatoes. We should also check for Irish accents, because potatoes are Irish.
Let's avoid any unfortunate connotations with exploding potatoes and Irish extremists.
Actually, Raikaria might replace 'Mafia' with 'IRA' in this game.
That's Raikaria's crazy theory. The mafia is actually the IRA, and not an Italian crime group, and they smell of potatoes, possibly from failed attempts at making potato bombs. Unfortunetly there's not enough for even Raikaria to make a crazy theory about players yet.
Alternatively to the mafia actually being the IRA and using Potato Bombs, Raikaria thinks Minoriko might be annoyed at all of us.
It's one or the other. Take your pick.
And yes, Raikaria is having fun with this 3rd person crazy random ranting.
