@CrackFoxJunior Wrex gained leadership over a small tribe when he was younger after the Krogan Rebellions and before killing his father. The youngest to gain such an honor in a thousand years and he was the last to kill a Thrasher Maw. Shep inspired him to continue his efforts to reform the krogan, but Shep had no knowledge about Wrex uniting the clans before TIM told us nor did Shep had any involvement in Wrex gaining clan leadership over Urdnot.
