He first appears at a meeting between the leaders of each Clan when Duststar suggests the first law for the warrior code, to "defend your Clan even at the cost of your life". He agrees with the other leaders that this should be part of the code.
Three seasons later, at a Gathering, he debates with the new leader of ShadowClan, Brindlestar. The ShadowClan leader claims that she has a complaint against ThunderClan. He tells her that they weren't the ones stealing prey and she hisses a retort that they weren't stealing, if they couldn't find meat to eat in their own territory. Vinetail, his deputy, gets into the arguement and asks when ShadowClan started hunting in brambles. When the branch falls down on the Clans, he is the second leader to ask if his Clanmates are alright. Brindlestar confesses to stealing ThunderClan prey.
He agreed with the other leaders to add a second law to the code, that borders should not be crossed.
