He also survived the attack on his clan by the Trees Enfolding Clan after being seriously injured during the battle. Anders Whittaker and Jessica Pheriss rescued him following that attack, taking him to Dr. Scott MacDallan. MacDallan and Irina Kisaevna were able to repair the physical damage after a long surgery.
