Throughout the series Edit
In Other Lives he trains Green Team (the selection course for SEALs trying out for DEVGRU), among them Clay Spenser and Brian who both are first in their class. He then states that he will release a bottom five list later that day that will end up sending one of the hopefuls home. He clashes with Clay over his arrogance. When Spenser finds out that he is on the list he tells him that it could be worse.
