Nathan began to see Victor as an even greater problem than Erin.  If allowed to go free, Erin might return to the stable for his horse.  But Victor and his real or imaginary fire "friend" on the roof of the tavern?  The last thing Nathan needed was for the tavern to burn down around him while he slept in his bed.  Besides, if Victor wanted to sleep outside, why on the roof?  Nathan had slept on the ground more often than he had in a bed during his life.  That was a soldier's lot.  If Victor wanted to play with fire, better to have it on the ground than on the roof of a tavern full of people.  Nathan looked around for Abia so he could voice his concerns.
