Lundgren knew the match was somewhat futile, and to be honest, after taking a beating at the hands at a bunch of children, his bones ached so badly. The prospect of breaking his poor hip in a pointless fight didn't appeal to Lundgren, so he decided to use his crafty brain to come up with a solution.
Now during the cold winter nights, Lundgren gets to warm his cold aching bones with Decus acting as his fireplace. Decus won the match without Lundgren showing up, and Lundgren doesn't have to mutter after his old body and drafty castles anymore. Well, being old and crotchedly, he probably still does anyways.
