[The Sleeper]

They are little kids who have actual swords and to say that they are in an unhealthy environment is a massive understatement, to which Little Waldet shows a greater propensity to respond. It is not a stretch to imagine that a fight got out of hand. I'm not sure how the particulars will matter though. Any pretext would do.

The tale of the rat cook had him feeding on his own children. This is part of that literary theme of the Freys turning on each other, as the various plot pressures start to mount up.
